Windows 10: No internet using ethernet cable

Hey,I have had my internet running for almost a year with no issues, now suddenly i just stops working and i am lost why.My PC doesnt want to connect to internet using the ethernet cable, wifi works fine and has no issues.Its not my cable as i unplugged it from my PC and on my laptop it works fine with cable.Its not the modem/router, its not blocked and i have already restarted the modem/router.I have tried to uninstall the ethernet in device manager, this uninstalls it but when i re-add it it says it didnt start.this is what i get in the events tabevice PCI\VEN_8086&DEV_1A1D&SU

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.

 

Ethernet cable not working.

You need to solve your problem one step at a time, e.g. like so:

• Connect your CAT5 cable directly to your router. If it does not work, replace the cable.
• Connect the cable to your TP-Link wall plug. If it does not work, reconfigure or replace the wall plug.

 

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.
