Networking :: Ethernet Cable Doesn't Have Valid IP Configuration?
Feb 10, 2016
Where to start so to begin with my issues started when we got a new router. We had issues with the old one so we installed a new router and got it working fine WiFi worked alright but Ethernet would not connect it my computer when I ran the troubleshooter said one or more network Protocols were missing from my computer I'm running windows 10 version 1511. I went on google on my laptop to start finding a fix and I must have tried every option in the book just about I am losing my mind over how to fix this. Finally I tried reinstalling the Network drive Uninstalling my current one going on google finding my most updated one ect. and now the issue is no longer about the protocols but its saying my Ethernet doesn't have a valid IP configuration

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...
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.

8 hours ago my computer was connected via Ethernet and functioning fine during online gaming.
This morning approx. 4 hours ago I awoke to notice the computer updated and restarted during my sleep. Now the network icon has an exclamation mark and displays "Ethernet doesn't have a valid IP configuration."
WiFi functions fine. Other devices connect to WiFi fine. PS3 is wired to a different port on the router and functions fine, so attempted to change ports the laptop connects to, with no success. Bypassed the router completely and went just Ethernet straight, still will not connect via wired connection.
I have powered off the laptop, router/modem with no success in rectifying the issue.
Here is ipconfig all ---
Code:
Microsoft Windows [Version 10.0.10240](c) 2015 Microsoft Corporation. All rights reserved.
C:WINDOWSsystem32>ipconfig allError: unrecognized or incomplete command line.
USAGE: ipconfig [/allcompartments] [/? | /all |
/renew [adapter] | /release [adapter] |
/renew6 [adapter] | /release6 [adapter] |
[Code] ....
I have checked network adapters and ensured drivers are up to date. Which they are.

Very frustrated!! I had internet connectivity prior to windows 10 upgrade. The above message is what I am receiving. Network Center states: Unidentified network. I have done the following: Taken modem/surfboard, router and pc down gracefully then brought back onlineUsed windows troubleshooterread thru (and walked thru) dozens of forums with solutions to other "similar" issues**I have tried to connect directly from pc to modem. I get the same results. I have zero connectivity from my pc so I plan on using a thumbdrive if I need to reload drivers. I'm about to revert back to 8.1 and call it quits..

I updated to Windows 10 yesterday and after a few quirks I got it to running as normal, or so I thought. I use an Ethernet cable to connect to the Internet but all I get when I diagnose is "Ethernet doesn't have a valid IP configuration". It used to work fine before updating by the way. This is what I've tried
Restarted the computer
Turned off the computer, waited a few hours, then turned it on again
Unchecked IPv6
Re-installed the LAN driver
Tried a different ethernet cable
Tried to follow the tutorial on this website for Windows 8 for this issue but when I type ipconfig /release, it tells me that "an error occurred: an address has not yet been associated with the network endpoint"
Another thing I've noticed, when I enable the Ethernet connection, my computer skyrockets to exceedingly high temperatures (over 99C according to the monitor I have). When I disable it or disconnect it it goes back down to normal. Not sure why this is happening.
EDIT: Looks like the temperature only rises when I check IPv6

After I installed Windows 10 on my computer I cannot connect to internet through the ethernet port. I've tried everything. I get the message that "Ethernet Doesn't Have A Valid IP-configuration". I tried to reinstall the network driver, ipconfig /release and ipconfig /renew as admin but it cannot find the "Default Gateway" and when I type ipconfig /renew it cannot connect to the DHCP server.

I am running Windows 10 demo version. I have problems connecting to the net. I am shown the error along the lines of "Ethernet does not have a valid IP configuration".
From command prompt I run "ipconfig/all" and here is the console's output:
When I run "ipconfig/renew" it fell through : I should add, I have no problems on Windows Vista however.

I've been having the above issue at different times and it is getting a bit irritating to restart the modem(router).How can I permanently fix it so that my internet can be online 24/7 without me having resetting the box?And how come it says that I have no IPv4 connection but IPv6 does have a connection?

My internet was working fine for quite a while after upgrading to win10, but one day both the wifi and ethernet stopped working. They both show a limited connection, or sometimes even fail to identify the network. The error message in the troubleshooter for both ethernet and wifi is 'doesn't have a valid ip configuration'. I have tried rebooting and resetting the router, re-installing network drivers, and restarting everything involved.
The wifi card is called "TP-LINK Wireless PCI Express Adapter" and the ethernet adapter is "Realtek PCIe GBE Family Controller" and is connected by a Cat5e ethernet cable.

I'm facing an weird problem in Windows 10. I've upgraded to Windows 10 from Windows 8.1. If I restart my PC then it shows my network connectivity is limited for both wired and wireless. After troubleshooting it says 'Ethernet does not have a valid IP configuration'.But if I shut down my PC and then start it again then there is not any issue in network.I was using a legit copy of Windows 8.1.

2 days ago, I was happily enjoying my internet when suddenly my internet stopped working, I checked it and it showed that the ethernet cable is unplugged. I have by now, tried reinstalling win 10 (lost all my files and drivers ) and few more things like automatically searching for updates online. I have a realtek family controller

I have been unable to do a direct cable connect. Settings are not available. In settings, to do a cable connect it asks for a name and ISP. There isn't any. I never had a problem doing this before and I can do it with my apple computer. It has now been 2 days trying to figure out how to do what should be the easiest connection. No problem with any wireless----not everyone has wireless! Your microsoft stores have a long way to go to match the apple stores. If you can't get a connection to the internet it is very difficult to communicate or download any patches.

I ran Windows 8.1 on my desktop machine a few months ago, and later upgraded to Windows 10. Everything worked great at that time, but since have replaced Windows with Linux. Now I'm trying to install Windows again, with the same 8.1 disk that I used for my earlier installation, and my ethernet connection isn't found. (this is a direct wired ethernet, not wireless) I've installed with a local user account, dug into every networking utility in Windows, but whatever I do the internet goes undetected. I've run the ethernet thru different routers, and even circumvented the router all-together, but no luck. Has my 8.1 disk "expired"?

A couple days ago I noticed that instead of having the ethernet in my taskbar that it is connected to wifi. I dont understand that because I have been using hardwire forever. To top it off my xbox connects via ethernet, but my pc wont. have tried the same cable that connects my xbox. I am pretty sure this is causing serious game lag, and i dont know what to do at this point. i cant access my router settings either. i type 192.168.1.1 and it doesnt load. that is the same ip address that i have always used before.
So this solution did work in a sense. Once reinstalled my drivers, my computer did detect that there was a ethernet plugged in, but it said the there was no connection. I disabled wifi on the computer, so it can only connect to ethernet. even tho it says that there is not internet connection through ethernet, everything is working great. It permanently has the Caution symbol over my internet.

My problem is i use a hardline into my computer and upon starting it up yesterday was greeted with the problem “no ethernet cable installed or connected”. I have replaced the cable already/restarted both the computer and router multiple times/did a system restore and none of those worked. Also disabled and re enabled the adapter multiple times.
The only thing that seemed to work or hint at the problem was a windows 8 forum that said to use an elevated command prompt to do “sfc/scannow” and that came back with errors. There was a “DSIM” command that was unable to find a correct download location.

The other day I was connected to the internet via Ethernet cable I bought around 3 weeks ago and it was working well with no problems, but for the past two days when I plug in my ethernet cable, my laptop doesn't detect it and it says "Network cable unplugged".

Win 10 32 bit will only load properly with Ethernet cable. Discovered this looping issue when I moved the PC and went to use Wi-Fi. Plug cable back in and everything goes back to normal. Troubleshooter doesn't find anything wrong.

My computer wont connect to the internet via ethernet cable. It works when the cable is directly connected to the modem, but when I run the cable into the wall output it wont connect. Ive tested that there actually is internet through the cable in the wall by connecting it to my Macbook, and it works perfectly. what can I do to fix this?

i recently updated to windows 10. I'm having some difficulties regarding internet through Ethernet on It. what usually happens is i am able to surf the Ethernet for around 10 minutes, then the ethernet adapter just quits on me. So i run the network trouble shooter and find you that it needs to reset the DNS, which it does successfully. After that my Ethernet doesn't work anymore till I restart the Laptop. my computer's wifi card is an intel wireless n 7260, and the other network adapter is a pcie gbe family controller.

So i recently updated to windows 10, and i noticed i wasn't connected to my Ethernet anymore, so i had to connect my PC to the wifi. Under my "network Adapters" it only shows "Qualcomm Atheros 802.11 1/b/g/n" I tried connecting another ethernet cable, but nothing happened.

I cannot seem to connect on Ethernet though Wi-Fi works OK. I have seen several articles about ethernet problems with Win10.
CABLING
First the network config:
Two notebooks, C and D are plugged into a switch and the switch plugged into the router. Now, the cabling is verified to work because computer C, running Win7 connects just fine and if the internet cables are swapped, computer C still connects just fine.
Computer D however does not connect. I did some other things to redundantly check too, just FYI.
So cabling looks OK.
ROUTER
both computers have fixed (reserved) IP addresses in the router.
The router sees computer C
but not computer D
Just FYI, if I turn on Wi-Fi, the router sees D on WiFi, but not the ethernet.
PING
Computer C can ping D
Computer D can ping C
Computer C can ping the router
Computer D cannot ping the router
Some investigation suggested the following, all of which I tried with no better results:
- Update the network adapter drivers (already current)
- Winsock posible culprit, so NETSH WINSOCK RESET and reboot - no change
IE used to find and fix these things pretty well, but here we have EDGE. Perhaps I'll try to install IE. Connectivity diagnostics are where IE shined over Chrome and Mozilla.
UPDATE: IE 9, 10, etc. are not compatible with Windows 10. So, the connectivity diagnostics just not as good in Win10. I can tell I am getting tired, as it's getting hard not to swear.
UPDATE: Added a pretty picture.

I was wondering if it's possible to utilize both WiFi and ethernet in tandem. I'm pretty sure some of you are going to tell me that I can only access the internet through one of these, up to my bandwidth limit, but that's not what I mean.
I'd like to access the internet through my WiFi connection, yet have a wired connection through my router to access the files on the other computers in my house.

I've been having problems with my network drives which seems to have happened after a recent Windows 10 'update'
In device manager I stupidly deleted a number of Windows adaptors under the Gigabit network connection.
Now I just have the Red Cross over the Internet icon.
Ive tried reinstalling Intel drivers but they stop at 'installing network drivers for Intel 82579v Gigabit network connection'
I then get a message 'cannot install drivers - No Intel (R) adaptors are present in this computer'
motherboard is is a Gigabyte X79 UD3 running F20 Bios. The network adaptor is onboard.
I can't seem to figure out why the computer can't detect the adaptor.
There is no ethernet controller in the device manager? And the network and internet page in settings does not give an Ethernet connection option?

i've been with this problem for months and i have tried multiple solutions offered by others on the internet, yet i'll give it another try here.
i'm using a powerline adapter directly plugged into the wall on my desktop. And it has worked excellent before, but suddenly someday it did not get a valid IP adress anymore for my pc, i have tried giving it an ip adress manually but without succes. i also tried updating the driver but there was no update.
my network and sharing center displays unidentified network and windows problem solver detects the problem 'network name' does not have a valid ip configuration.
