Windows 10: Ethernet cable not working.

I've been trying for hours now to fix my Ethernet cable with no success. Ever since I had a power cut yesterday in the WiFi options it has displayed my Ethernet as "Unidentified network" and has granted me no internet access. I've troubleshooted the problem and it said "Ethernet" doesn't have a valid IP configuration. I googled how to fix this and it said to type "ipconfig /release" and then "ipconfig /renew" in Command Prompt. I did the first command but when I tried to do the second command it stated something along the lines of "Ethernet cannot be changed while it's media is disconnected". I googled how to fix this and it said to do "netsh int ip stop" then "netsh int ip start". Tried to do this and it said that the command was not found. If someone could help before I utterly **** up everything on my computer help would be much appreciated.

EDIT: Not sure if this matters but the Ethernet cable does not connect to my router directly, it connects to a wireless TP-LINK wall plug which is linked to my router wirelessly.

Ethernet cable settings

Hi Campbell,

Thank you for writing to Microsoft Community Forums.

Please reply to the follow questions to get a better understanding on the issue:

• What is the model number of your laptop?
  
• Do you have a yellow exclamation on the network icon after connecting the cat 7 cable?
  

However, you can follow the troubleshooting steps from
Fix network connection issues in Windows.

Also, I suggest you to check the laptop manual or laptop manufacturer to know whether the Ethernet port of your laptop supports cat 7 cable.

Hope it helps.

Computer not recognizing Ethernet cable

Hi Vijay, I appreciate your help.

I will try each step even if I've already done it, just to make sure, and post my results.

A. When I troubleshoot internet connections, it tells me “Plug an ethernet cable into this computer” and says my cable might be broken or disconnected. However of course i have tried a different working cable with no luck.

when I troubleshoot network adapter, it says “plug an Ethernet cable into the network adapter ‘Ethernet’” which of course has already been done so it is not recognizing it.

B. I tried every suggestion/step listed (except for the wifi troubleshooting since my computer doesn't have wifi) and none of them worked.

C. When I run the windows update troubleshooter, it tells me “download and install pending updates” (Maybe it is not up to date because I tried reinstalling windows 10 to see if that would fix the internet, but it did not. I updated it like last week or
something like that) but of course I can't download the updates without internet. If I click “apply this fix” it tells me to plug in an Ethernet cable. But i believe windows 10 was up to date before this issue even began because I updated it just a week ago.

D. I do not understand this step. The guide is confusing to me. It also appears that I have to download tools in order to do this repair. I cannot download anything because my computer cannot connect to the internet. I don't have a USB flashdrive. I did
try reinstalling Windows 10 though and it did not help.

 

Constantly disconnecting with ethernet cable

Hello,

Thank you for keeping us posted on the status of the issue.

I suggest you to check if rolling back the Ethernet driver helps to resolve the issue. Follow the below steps.

• First of all, Press Windows logo + R from keyboard. It will open
  RUN.
• Now type devmgmt.msc and press Enter to open Device Manager.
• You will see all the device list of your PC. Expand Network Adapters

Rollback driver

Double click on your Ethernet driver in Device Manager. Then Click on
Driver tab and select Rollback.

Important: If your drive is performing well and there is no error, Rollback driver button will be grayed out as an option.

If it still does not help, I suggest you to reinstall the drivers for the Ethernet driver and check if it helps to resolve the issue.

Note: Once you uninstall the drivers the Ethernet adapter device will be disabled and you won’t be able to connect to internet. So it is advisable to keep all the installer files as a back up in your hard drive.

Write to us with the results for further assistance.

Thank You.
