Q: Solved: Such thing as an Ethernet switch that doesn't need power? Question about ethernet run


I have an ethernet cable run in my house. What I need to figure out is if there is such thing an ethernet switch that does not require a power source. (or something that can get this situation resolved)

Here is my situation:
I have a cable ran to my basement, and have a bedroom directly above the basement that needs an ethernet run. It is not possible for me to run a completely new cable from the original starting point, so I was somehow hoping to use the cable going to the basement, put a head on it, put it into a switch/hub/splitter and run a cable out of it to the room directly above, and use the other cable coming out to stay in the basement.

Is there something that can do this for me? Is there a better way to do so? What would you suggest? Thanks!

UPDATE: Please refer to post #4 for more details.

I've had trouble connecting to my own internet and have no wireless. I'm using my neighbor's wireless and it's really slowing her's down.

I've tried restarting my laptop (it usually works) and then reinstalled the device under "device manager". It's not the cord, I've checked with my neighbor's laptop and it works fine.

I use a Sony Vaio VGN-NS140E with Windows Vista SP2. I'm not sure what other information to give.

Any suggestions welcome!

Hey, all. For a couple years now, I have been using a 5 -port Linksys Etherfast switch to hook a Panasonic blu ray player & DishNetwork Box to the internet via my home network. I had the switch plugged into a gaming adapter. Worked fine, until I had to replace my router. Was using a Linksys WRT54G router and the switch & router communicated flawlessly.. didn't even have to set it up manually when I first added the switch. Did all this to avoid dropping more wires into my back bedroom.

I upgraded to Cisco (Linksys) E3000 Gigabit router, and the switch will not "talk" to the new router. DHCP's enabled, and both the bluray player & Dish box tried to autoconnect using DHCP.. no dice. Tried several hard resets on all devices mentioned above, even firmware update on the new router. No dice.

So here's my question : do you think it's just an incompatibility question? If I buy an Gigabit ethernet switch, do you think that will fix the communication problem?

I was thinking if you go gibabit to gigabit.. It might be more compatible. I wanted some expert opinions though, before I go dropping another $30-40 on a new switch.

I read about creating ethernet bridges using DD-WRT firmware, but it seems daunting. I am not a complete noob, but it seemed beyond what I wanted to bite off.

Thanks in advance you guys & gals!

Can we connect Power over Ethernet (PoE) Adapter just like this one D-Link Power over Ethernet (PoE) Adapter Kit with any Ethernet switch ? I have a Belkin 5-port 10/100 switch can it be powered by PoE ?

How it will be setup.

A:Can I use Power over Ethernet (PoE) with any switch ?

If you are asking if you can connect this device to a NON-PoE switch and then have PoE on the switch the answer is no. If you are asking if you can connect this device to a switch and make one port PoE on the switch the answers is no. The D-Link device is PoE only on the D-Link device. I hope that helps.

If you need PoE on a switch you need to buy a PoE switch the electronics inside the switch are different. However, you can plug NON-PoE devices into a PoE switch without problems. -WS

hey guys i have a quick question bout a situation i have going on. the computer i am now on is hooked up into the internet via a wall ethernet jack, which is hooked into an ethernet switch (or hub i think) in another room where the cable modem is located. the tv that i play my xbox 360 on is a good 10 feet away or so, and i want to get connected onto xbox live from there.

i have an ethernet cable that is long enough to run from the xbox itself to the wall ethernet jack that the computer is hooked into.

what my question is is that if i buy another ethernet switch and hook it into the wall jack, and then from that switch run another ethernet line into the computer which is literally right on top of the jack and then another line from that switch into the xbox 10 feet away, if this will work since the wall jack itself is hooked into another ethernet switch in another room.

i can kinda guess that was kinda annoying to follow but i just wanted to explain everything to avoid confusion. help would be really appreciated . thanks guys

Hi all,

I was wondering how an Ethernet switch forwards packets of network information. Does it send the packets to all outputs? If so, is it like a hub? Does it know where computers are and only send the packets to the right place? If so how would it know where the computers are?

I've been wondering about this for some time but haven't been able to find the answer.

Hello. I have the Ethernet doesn't have a valid IP configuration problem which I've googled and discovered is common and well known, i.e., make sure the adapter is set to obtain the IP automatically, and if that fails update the drivers.

However... I need help getting the drivers installed. I don't know where to get them from, or where to install them to.

The computer that is not connecting either via ethernet or wifi is an Acer laptop running Win 10. I have a Lenovo running 8.1 that does connect, thus I must use the Lenovo to get the drivers, then transfer them to the Acer and install them.

Can someone please tell me how to do this? Where do I get the driver files (specifically, how do I know which files I want) and then how to install them once I've transferred them to the Acer?

Thank you

A:Ethernet doesn't have a valid IP configuration ... newb question

Provide make and model for the Acer laptop, so we can look up the network interfaces. Also might be nice to let us know if you're using wired Ethernet or WiFi on the Acer machine. If you can provide that info, we can get you headed in the right direction. HTH,

PS: I keep an el cheapo StarTech USB 3.0 to GbE adapter around (Newegg: $22) for when NICs go south. You can plug it into most PCs (the drivers load automatically) and use a fast, simple, wired Internet connection to fix a machine that's having problems with its built-in network interfaces quickly and easily. In these days of Windows 10, I use it at least once a month!

I am having a problem with an ethernet switch that is locking up, trying to find the root cause.

The switch is a 16 port, 10/100Mbps, Linksys model EZXS16W. I have three computers connected to it:
Computer "A" is a Windows XP Pro machine running a FTPD server (Guild FTPD).
Computers "B" and "C" are CPU boards in an avionics box, both running VxWorks.

When the avionics box powers up, computers "B" and "C" attempt to communicate with computer "A", both using port 5000. After a few seconds computer "A" reports an error that it is unable to communicate with computer "B".

At this point I tried to ping computers "B" and "C" using computer "A" (ping fails), And tried pinging all three using a fourth computer connected to the switch (also fails). I concluded the switch is locked up. Power cycling the switch restores operation until it locks up again.

I tried two other identical EZSX16W switches (same revision, same firmware) with multiple avionics boxes:
Two of the three switches always lock up when used with the first avionics box.
None of the switches lock up when used with other avionics boxes.
Two D-Link switches do not lock up when used with any avionics box.
None of the switches lock up since I updated software in the first avionics box.
All of the above results are the same if I use another computer "A".

A:Solved: Ethernet Switch Lockup

I'm not familiar with that switch. But if the customer wants to know why, you would have to do some more exhaustive troubleshooting. The first step is to look at the switch port the problem avionics box is plugged in to. You need a switch that can give you detailed information on what is happening on that switch port. Whether the connection is dropping out of full duplex, if there are collisions, runts, giants, CRC errors, etc, etc. To get that type of information you're looking at fully managed switch. If those don't give you any clues, you'll then have to either connect a hub in line or port mirror that port so you can do packet captures with a sniffer.

I have a curious issue, so I figured I'd see if someone can fix a problem for me for a change.

I recently upgraded to a 35/35 Internet connection. When I connect my computer directly to the router, I get the full bandwidth on a test at However, whenever I use any of my gigabit switches between the computer and the Actiontec MI424WR router, I get much more leisurely upstream connections.

This seems to be some sort of issue with the cheap SOHO switch being throttled by the 100mbit port on the router. Obviously, the gigabit port on my computer seems to be smarter than the gigabit switch ports.

It seems clear that I probably have to replace the switch with a better model, but I don't want to buy a more expensive switch without knowing that it's really going to solve the handshake issue.

Any suggestions or ideas on how to beat this into submission would be appreciated.

Hello everybody, I am in some distress, and would greatly appreciate your help

Here is my set up
Alright so my laptop and PCs (a) and (b) have the access to the internet. however my router sees only these three devices connected, as if my ethernet switch was not connected to the router. My problem is that the switch seems to work sometimes. Vonage is apparently having issues with the network setup so it doesn't work, same with my PS3, however the PC hooked up to the switch as well, sometime has internet and sometimes it doesn't. When it does have internet, Windows Xp pops out saying that there is an IP conflict with another PC on the network and then the connection is out. Any ideas of what is screwing up on my network? Any help would be greatly appriciated.

PS the ethernet switch is made by company Airlink
the modem is made by RCA
and the router is made by Linksys if that helps

A:Solved: ethernet switch possibly not recognized by my router

The exact make/model of the modem, router, and switch would be real useful here.

What you seem to be describing is a flaky switch or cable, not much can affect a simple switch in that manner.

As far as the duplicate IP addresses on the network, that could well be a different issue.

Turn off everything on the network, ALL the machines and any other network device like network printers and NAS drives.
Turn off the router and modem.
Turn on the modem, wait for a steady data light.
Turn on the router, wait two minutes.
Turn on the network devices and computers, one at a time.

This issue is usually caused by resetting a router without resetting all the network connected devices.

Another issue that will cause duplicate IP addresses is assigning static IP addresses to devices that conflict with the router's DHCP address range. If you require static IP addressed devices on the network, they should be configured to be in the same subnet but outside the address range defined for the DHCP server.

I recently purchased a NAS Drive which works ok. However I have also found out that my Sky Hub only supports <100Mbps.

The problems I have is when copying to the NAS drive I only get write speeds of around 10-12MBps which sounds about right being around 1/8 of the 100Mbps. Also when I stream I get a lot of buffering/cut out with any HD content streaming to my Xbox 360.

I just wanted to know if unplugging everything from the router and into a gigabit Ethernet switch then connecting that to the router will speed everything up? Or would I be better off going all out on a pricey router?

Basically am I right in thinking the switch will bypass the router for anything not using the internet?

As my PC will be moved upstairs soon where there is no way to get a ethernet cable any more,
I will be forced to go wireless...
I have never wanted it and never used it except on my mothers laptop witch is obviously built-in.
So my experience with wireless stuff is very low...

some fact that may play a role for your comments:
-from PC to modem/router threw the walls will be about 8 yards max.
-there is a chimney in the direct path from PC to modem/router.
-there is barely any metals used in the house although the modem is placed next to the water-main.
-the laptop of my mother never had any issues and is about 2 years old cant tell you the what hardware it used ATM.

Now what I want:
-I want my 6.4 MB/sec speed (other wireless devices dont play any role > mom laptop (80% facebook and 5% mails and 5% searching the web and the rest is youtube lol ; and the smart TV really doesn't do anything except for streaming some video clips very rarely.

- I prefer an internal piece of hardware witch I have a PCI slot for with the room. Although I would also like to be able to give internet to multiple PC's or whatever , ya never know ; LAN party for example...

Sometimes the internet connection status will initially say connected, but when I try to access a webpage I get the error ďDNS_PROBE_FINISHED_BAD_CONFIGĒ on chrome, then the connection status changes to limited. I can connect to the internet via Ethernet cable at work.

I used to have a static IP reserved for my laptop, but then removed it to see if that would make the Ethernet connection work (it didnít).

I have also reset the modem, run troubleshooting, reset my laptop numerous times, and run ipconfig release/renew. I also changed the name of the router, then changed it back and re-input the password.

Partway while trying these things my laptop changed from identifying the connection as Wire1 (name of my router), to calling it unidentified network (no internet access). My Lumia 520 windows phone also became unable to connect to the router (it says Wire1 is not responding).

I've tried many different versions of SiS900 drivers but it simply won't work.

When I tried the setup.exe file that came with the official driver, the install would say "Update Driver for PnP Device Fail. Setup will exit".

That's when I simply forwarded the windows hardware installer to an XP folder i found in the zip file. But still, it doesn't work.

I need to buy an ethernet card for the second PC which I will do later on today assuming I'm correct in the following understanding:

The server PC only has one ethernet card in it and as it's not my PC I'm not in a position to stick in an extra ethernet card. Everthing I've read on the internet says you need TWO ethernet cards in the server PC, one for the broadband to come in, one for it to go out to the clent PC.

As the internet connects by USB to the server PC, does that mean I can just run an RJ45 connection between the server PC's single ethernet card and the second PC's ethernet. And then just run Internet Connection Sharing?

Hi, I have a question on how dsl works? My friend has jackflash dsl and her pc broke and she had another a pc with windows 98 to hook it up to. But,,, i think it has viruses or spyware and had trouble getting it connected. So i thought about bringing her dsl box home with me because i have the dial up of the dsl account and we both have same phone numbers in the same area code so didn't know if you can hook up a dsl connection on any phone line in ur area and still get online and put there user name and password in and get online? Just to see if it's that one computer that is malfunctioning? If not then i will bring my xp pc over to her house tomorrow and try to hook it up. Wanted to save a trip of hauling my pc to her house if i could check it here. thanks, kim

Got an odd one for you, but someone might have run across it.

In addition to software security devices when accessing the Internet, I use hardware security as well. Since being disconnected from the Internet is the best possible security, I use an RJ-45 coupler in the Ethernet cable between my computer and the cable modem, keeping one or other side of the cable disconnected except when I'm actually using the Internet (downloading mail, etc.)

This is quite convenient, but the Ethernet connectors invariably break after 100 or so connect/disconnect cycles, and the cable segment has to be replaced.

The best solution, if anyone has ever seen or heard of one, would be an on/off switch designed to link two RJ-45 Ethernet cables. Not as good would be a little two-port Ethernet "hubby", such as used to be available for a while 10 or 12 years ago, with its own power supply; I could then use an ordinary 120V AC on/off switch to control the Internet connection by powering the hubby up and down. But I can no longer find any of these hubbies.

Any info on either of these devices, or suggestions of better alternative methods, would be much appreciated. Thanks.

We have several computers on a network attached to a router. My son uses his PC and plays games on line using the Xbox. Everytime he wants to switch from one to the other, he has to pull the Ethernet cable out and put it in the other unit. He isn't close to the router so its impossible to set up two separate connections. Is there anything out there that would serve as an A-B switch where he can hook up the Ethernet line to the switch, then run another two shorter wires out to the PC and Xbox. It would be nice for him to be able to go back and fourth without having to crawl behind the Xbox and attach.

Another thought for changing my network for printer only sharing.

All things being equal, which hardware item will be better for printer sharing - Hub or Switch. I don't want to have to redo my cabling.

I understand a hub or switch will change the direction internally, so I don't have to buy any cross-over patch cables, but just plug each computer in to the hub or switch - right?

The other alternative is to buy a second cheap printer, but that entails cartridge additions at a later date.

So, I have my modem (SBV5120) and a 4 port linksys router that I had connected to my desktop and laptop computer. Power went off and shut everything down, beside the laptop obviously since it has a battery. Andd, now when I turned my computer back on, it said "100Mbps Connected" but I had no interent and it looked like the light from the back of my computer was orange and flashing.....So I tried bypassing the router and going directly from my modem to my desktop and it would stay at accuirering network address.......and then I try to click cancel and it wont let me, then proceeds to freeze so I have to end explorer.exe and you know the deal.

After that not working with or without the router, I tried to use the USB port on my modem to my computer, that would do the same thing - get stuck on accuirering network address. So now I'm stumped and not sure what to do.....My laptop works fine going through the router and going directly from the modem.

Hello. Do I need an Ethernet hub, switch, or even a router to have my Ethernet VOIP telephony box to be hardwired "separately" from my cable modem and NOT be part of my hardwired wireless router's ports???

My Objective/My Plan:

This is for home/residential networking. To have two (2) hardwired networking hardware items: 1. (1) VOIP box... ...and... 2. (1) wireless integrated router BOTH hardwired off of the same cable modem of my cable ISP. I need either a hub, a switch, or even a router to connect both networking hardware items to the cable modem. Also, I MUST BE ABLE to connect to the Internet at the same time for both the VOIP box and the wireless integrated router (the Internet) if necessary. My current wireless integrated router will serve as my wired/wireless networking device for a desktop computer, a laptop, an Internet streaming radio, and a Wi-Fi Smartphone; but the wireless router *WILL NOT* serve my VOIP telephony service. Why? See: "Reason".

For your information, the VOIP box offers an incoming Internet connectivity, an outgoing traditional telephone jack, and a power port for a power adapter. No Internet bypass Ethernet port on the VOIP box.

Also, be aware that my cable ISP company is NOT the same as my VOIP company. This does not make much different on the networking hardware setup. The cable modem itself has ONLY one (1) Ethernet connection too.

1. You could complete this in two different ways however it is dependent on what the current router is for your main internet connection to client computers. One way is to connect a separate router to one of your main routers LAN ports. for example connecting the internet port to the LAN port. Then all you need to do is add the VoIP clients to the added router and it will be completely separate from your computers due to a technology called NAT.

You would disconnect one ot the PCs from the router. Then connect an ethernet patch cable between the disconnected port on the router to a port on the Dynex switch. Then plug the PC into the switch. If the printer is a networked printer, also plug it into the switch.

I am designing a test system that has three 8-bit ethernet microcontrollers connected through FPGAs to some non-standard serial buses transmitting and receiving 16-bit serial data at 1Mbps clock, at some data rate (maybe up to 500 messages/sec each). A PC connected to the ethernet switch will send commands to the three microcontrollers, and will process the data they send. The PC is a Core 2 Duo at tbd speed with tbd RAM, and software to talk via ethernet will be an .exe compiled from C++ source code. Based on years of experience I think the PC can keep up, but I don't know about the ethernet switch.

I don't think a $50 5-port Linksys or D-Link home switch is going to handle this, it needs to buffer data so messages don't get lost. I don't need a router or DHCP server, just a decent switch.

Any ideas? This is for work so money is no object (but would like to keep it under $2000).

If so, where are the Settings to do it, and how would I go about it ?

A:ip conflict with ethernet switch

Because you have residential service which will only give you one single public IP. By putting in a switch, you are causing both laptops to request an IP via DHCP. Frankly, I'm surprised you're even getting both laptops to get an IP from the DHCP server. You need a router which does NATing to allow simultaneous network connectivity for both laptops not a switch.

Anyway I have now decided to go a different route and I purchased a Vonets wifi bridge, which works well. My question is this - I have an old Netgear DG834G router and I would like to use this as a network switch so that I can plug my bridge into one of the ethernet ports and draw off from 2 of the other 3 ports to feed my printer and Sky HD box.

I plugged the vonets into port 1 and then a cable to both my printer and my sky box and nothing - then I went into my netgears homepage and disabled DHCP, and hey presto I got a connection on my sky box. I assumed that was that until I tried to print and the printer was not available. I have tried loads of things since - static IP on the printer (I usually have it static anyway as my work laptop doesn't like it otherwise), manually configuring the network on my sky box, changing some of the settings in my netgear router but I cannot get it working.

I use a cable internet connection. My previous modem had a "standby" switch, so whenever I left the computer I would set the modem to standby, to prevent hackers from having access.

I just got a new modem (internet and telephone) that has to remain on at all times in order for the phones to work. For now, I've activated my EZ firewall, which I haven't used in the past because it would cause some problems with some apps.

I've set up two routers (one a primary router and the second as an access point to extend my wifi). They are currently in the same room connected together a by 1 metre cable and everything is working fine.
However, I need to move the second router upstairs and trying to replicate the connection between the two routers. The house is wired with network points and cables which all feed into a 24 Port Planet 10/100Mbps Ethernet Switch.
I've located the wall socket/ethernet port number (No. 6) from which the primary room is located and connected and similar the second router in the upstairs room (No. 2).
As its going into an ethernet switch, I thought that should automatic connect routers on the network. However, when I try to access the second router (via WIFI), its not connecting to the internet which is likely because the two routers are no longer connected.
I tested the two sockets (No. 6 and No. 2) with one of those cable testers and I did get a signal on both ends, so not sure what is going on. To my mind, the routers should be connected.
Can anyone help?

A:Connect 2 routers via Ethernet Switch

From your description it should work.
Go back to step one with two routers connected by the 1M cable and double check you get a wifi connection to the internet.
Plug Primary router into wall socket and secondary router into other end of cable, before the switch - check connection.
Recconect switch and plug secondary router to switch with 1M cable - check connection.
Reconnect switch and try secondary router in desired location - check connection.
A bit of hassle but will identify where the connection is failing.

My PC can find the wifi and connect but the only way I can get it to connect is by pulling out the blue Ethernet cable from the actual pc. (When I say connect, I mean it is "connected" already but not in use, the small box appears for the ethernet cable rather than the wifi icon)

I would like to know if there is a way to either run the wifi simultaneously with the Ethernet cable plugged in or if there is a way to "turn off" the Ethernet connection from my pc when it goes down, so that I dont have to keep unplugging it.

I am not very technically minded and am worried if I go into advanced network settings etc that I might not be able to get the Ethernet working again once it is plugged in and back up and running.

Any advice would be appreciated, thanks.

A:How can I switch to WIFI from Ethernet instantly??

You can have both plugged in and still work. Each NIC is assigned a metric and the NIC with the lowest metric will be used. If in your are the wired NIC is still seen as available but in fact it's having problems the computer will still try and use it unless you unplug the cable. If your computer supports a feature called LAN/WLAN switching that may work in your case that may work or may suffer from the same problem in which the wired NIC is still detected as connected and it won't switch. If you are only having an issue with the wired connection why not just stay on wireless?

Say I need to shut off internet access in my home to prevent my teen from having the temptation to play multiplayer games at all hours. I'm thinking that I could insert a timer switch in the ethernet cable that would disable one or two of the wires in the CAT-5 cable, rendering internet access inoperable. At 6 AM, when we need the internet up, the switch would restore the connection with no fuss (i.e. rebooting of routers, laptops, wi-fi routers, etc.). I need it to operate without daily intervention on my part; the internet goes off at midnight, comes back at 6AM. Ideally, it would deal with DST on its own too.

Since it's not the P/S, it's either the MB or the power switch. Disconnect the power switch from the MB connection, then plug the system in. It should NOT power up by itself, unless the BIOS is configured that way. In any case, short the two pins for the power switch briefly, and it should act just like you pressed the power switch. If so, the switch and/or wire is bad. Otherwise, it's probably the MB that has the problem.

I have this major issue with my MSN messenger (on my PC) whenever I connect it to a ethernet switch so I could use it (my PC) with my Laptop, so together both have internet connection.. my MSN messenger works fine and it could sign in easily, but when I disconnect my ethernet switch and connect to just my modem, my MSN messenger says it could not connect to the internet or that there's no internet connection where there is! (I forgot which error code but its well known, I've searched before and it said it could be the anti-virus etc but I have no problems with my anti-virus and programs it monitors). Anyone know how to stop this stupid silly error with Live Messenger?

A:Live Messenger works when I connect it to a Ethernet switch?

Can you ping once you use the modem? You might not be authenticating to the WWW properly and Msn is blinded with connectivity by the modem being unable to do so.

i recently built a third computer for my network, added a cable modem, and got what i thought was an unbelievable deal on a linksys ethernet switch (ezxs44 4 port)..... free.
now for the problem: i have an ericsson pipe rider cable modem, 3 linksys lne100tx nic cards, and the ethernet switch. i've treid to connect my machines and the modem through the switch the same way i connected the 2 computers before(pc to pc with cat 5 cable), it didnt work and it locked my system.
basiclly i am asking for somone to tell/show me how to hook everything up so it functions correctly, i've tried to no avail (ive reset all the configurations for the nic card in my main machine and am only running it with the modem (the original windows/roadrunner software configuration). do i have to change the cat 5 wiring diagram?, what seetings should i use on the nic cards?, and what do i do with the cable modem settings.

let me know what you come up with(i'm getting desperate, girlfreind...........MY computer)
thanks again

I would think one of your cables is wrong.

check the ends of the cables, make sure the same wire colors are going to the same pins, sounds like you have a crossover cable going from modem to switch.

So a couples of days ago my computer lost connection a few times, but it got back up running without any problems, yesterday however I had huge problems browsing trough the internet and had problems connecting to pages several times, but downloading worked just fine, but today I'm not able to do anything, it keeps disconnecting and reconnecting, but when its connected the connection is so bad that I can't access a single site.
I know it must be something wrong with my computer, because I've tested two different cables in two different ports, and I know one of the cables must work since I have no problems connecting to the internet on my Xbox 360, and all the other computers in the house have no internet problems what so ever, including the wireless connection on my laptop, and I also run into the same connection problem even in safe mode.
I noticed that the light on my ethernet port is solid orange, but usually it is green, and I've tried to do a virus scan to check if that might be the problem, but I doubt it since I haven't accessed any pages I don't usually visit in a while and it didn't find any viruses.
I have had some problems with the ethernet port before, but nothing that was permanent, I have experienced that my computer has had connection problems while everyone else in the house have had no problems, but after waiting a bit it suddenly reconnects and has worked just fine for many many months, and I've only experienced this pr...

The laptop (XPS M1330, Vista) doesn't connect to our network. It recognizes available signals but doesn't connect. Other computers connect fine to the network.

Winsock fix repairs the issue after one reboot but the next reboot reverts the progress. Command-line solutions (netsh int, many other flags on netsh) fail to make any headway. Not a card issue, an external wi-fi adapter doesn't connect either (with proprietary driver/software) and the wi-fi connects through a Hiren's boot CD. We tried giving it a static IP but that doesn't help at all.

My diagnosis is a low-level software issue. SFC "discovered" and "repaired" some broken system files but the issue persisted. I believe we've run an MBAM quick scan but I don't want to waste my time with a full scan on the basis that a virus wouldn't get rid of wi-fi connectivity but leave wired in tact.

We've tried all we can on this machine and it's getting very frustrating. If anybody here has experience with this issue, please enlighten me. I've had it for four days with no semblance of success (besides the one-time winsock fix).

Over multiple devices on the network, wifi works (including this laptop I'm running on). However, any time I try to use ethernet (including on this laptop), there is no internet connection. The error when troubleshooting is Dns server not responding. While on ethernet connection, I can access the networked printer, but cannot access the default gateway (so connection is going from room to the modem, and through)
I have tried restarting the wifi/lan modem, which then connects to another router down stairs which I haven't restarted (my dad won't let me). I have tried flushing dns, uninstalling and re installing the adapter, starting in safe mode with networking.

I wish to run internet on both the systems, for that I bought a USB-to-ETHERNET connector and an ethernet cable, so that I could connect USB end to the desktop and the other end (with ethernet cable) to my lappy, and could be able to share internet connection. The USB-to-ETHERNET connector came with an installation cd which I have installed already and I have setup the whole connection but unable to share the internet connection. May be there is some configuration problem or so.. Internet is running fine on desktop. Please help...

Been having issue for more than a year. When my provider (Charter cable with static ip) drops my internet connection I have to start "at the wall" meaning reboot cable modem then wireless router then reboot laptop to reconnect to internet. Takes 1/2 hour. Charter seems to be dropping internet more and more so this can happen once per week or sometimes every day or 3. Have narrowed it down to this. With internet working just fine. Can use wireless from phone to surf web. Can even enable wireless adapter on laptop and connect to internet via wireless. So internet is not the issue. I very seldom use wireless and instead use my ethernet connection. I keep wireless adapter disabled. Very simply, internet is working. I am using ethernet connection. All is good. Simply unplug ethernet cable from laptop then reconnect ethernet cable. I have no internet until I reboot my laptop. Reboot works fine but getting tired of having to do so every time Charter drops my internet. John

I have a brand new PC workstation.

Everything was fine, until recently, when I turn on my PC, I don't get an immediate internet connection. This is happening nearly everytime now with some frequency.

I reset the router/modem and everything is fine after that, so all is good.

But it is still frustrating. I get, "Ethernet doesn't have a valid IP configuration".

I googled this and it appears I am certainly not alone.

The following to assist you are screenshots of my 'ipconfig' and 'Network Connection Status' before (unsuccessful) and after (successful) internet access:

You will see from the above that there is certainly something different with the data...

I'm sure it is something so simple.

Incidentally, I did find a nice youtube 'tutorial' in relation to this subject title about manually configurating the settings:

I bought a new router (Cisco Linksys E2000), that emits a blue light if your device is gigabit (1000 Mbps) and a green light if it's 100Mbps. Whenever I turn my computer off, the LED is blue. Also, in my BIOS (Gigabyte motherboard) there's a testing utility that can test the speed of your Ethernet cable. I've done this and it says that it's gigabit. I turn on my computer and all through the POST and "Starting Windows" screen, it's gigabit. But once my computer gets to the Windows login screen for Windows 7, it switches to 100Mbps and stays there as long as the computer is turned on. I've tried logging off, and it still stays at 100Mbps. What's going on? It's gotta be a Windows problem.

A:Windows 7 doesn't like Gigabit ethernet?

this is from Cisco site =
Gigabit Ethernet (10/100/1000 Mbps) ports for faster file sharing with other Gigabit devices

It may be that you computers network card is not Gigibit [10/100/1000],so it changes from blue to green . your network device may only be 10/100 check the back of the computer where the cable plugs in from the router, it should be stamped 10/100 or 10/100/1000
also check device manager and see what network device is on your motherboard

Hello all, just joined...first post here.

I'm having major network connection issues. This one is baffleing, and that's putting it simple. I'm not computer illiterate by any means and I don't consider myself a newbie either. With that said however, I'm no guru but do know my stuff somewhat.

Here's my dilemna...and I'd like to go ahead and thank you all for you help ahead of time.

I'm running a Windows Vista desktop and laptop. There's internet sharing via Netgear Wireless G router (WGR614) and ISP is Comcast. Wireless seems to be fine however ethernet is acting up.

I'll try simplifying this possibly by listing my observations:

-Wireless is fine.
-Modem to router (via ethernet which is really weird) is fine. Router shows it's receiving a connection and it no doubt is as the router's broadcasting wireless signals...and strong ones at that.
-Laptop and Xbox 360 pick up strong wirless signals extremely well and perform as such. The laptop surfs the net without any latency, same goes for the Xbox 360 online gaming. In games where your connection strength is displayed (Call of Duty 4 multiplayer) the bars are all filled denoting max signal reception.

****Here's where the problem really lies******

-Can't connect desktop or laptop (with wi-fi capability off) via ethernet through any of the router's four LAN ports.
-Can't connect via ethernet DIRECTLY from modem to desktop or laptop.

We are having some concerning issues with our modem. Our wireless works perfectly, all our phones connect as well as our roommate's laptop. Yet, the two devices we have connected to our modem cannot connect to the Internet via ethernet without having to reboot the modem. It's really bizarre.

The computer runs on Windows 7 and the other device is our Xbox One. Both have issues connecting to the Internet without rebooting the modem. It has been weeks of this!

Our Internet is provided by Mediacom in Central Illinois.

We've tried un hooking the ethernet cables, no luck. Switched out the cables, no luck. The only thing that works is rebooting the modem.

A:Wireless works, but ethernet doesn't! Help!

It sounds like it maybe an issue with the modem/router , as it happens on two devices with two different cables - that would be my suspicion

So... I just updated from win 7 to win 10, as I got it for free. All went smoothly, but there was no ethernet connection. I'm running a custom built pc, connected to my router via ethernet cable.

At first windows detected the cable, but said: ''Ethernet doesn't have a valid IP configuration." I was on about around the settings, and deleted the ethernet network from windows' settings. I thought it would come back by just re-plugging the cable. This didn't happen. What happened was, that the whole 'Ethernet' tab disappeared from the 'Network & internet' menu!

I also don't have 'Wi-fi' or 'Airplane mode' tabs in the menu... Well I have a pc that doesn't have support for wifi so that might be why...

Does anyone have a clue on how to get win 10 to detect the ethernet cable, and maybe that way bring back the 'ethernet' tab?

Oh, and I tested the ethernet cable on my laptop (running win 7), and it worked fine.
Thanks in advance!
