Windows 10: Ethernet not detecting cable after windows 10 update

I am having issues with my ethernet adapter detecting the cable. I have tried uninstalling and reinstalling, resetting the network setting, updating drivers, and the troubleshooter. I don't know what else to do, Windows does not think anything is wrong just that there is no cable. Please help.

:)

 

Windows 10 after upgade to 1709 if keyboard not plugged then ethernet device is not detected.

When I start my windows 10 (1709 build) without plugging keyboard and mouse, it does not detect Ethernet card.

Mother board is of Intel and Ethernet is on board (integrated).

I have also installed latest Ethernet driver by auto updated drivers from internet.

Steps:

Shutdown pc

Remove keyboard and mouse

Keep lan cable plugged

Start pc

Ethernet device is not detected. It shows in list in Device manager screen. but with Yellow triangle.

Then I need to plug keyboard and just do a hardware scan then Ethernet is detected and all ok after that.

When I start with keyboard and mouse plugged in then it detects Ethernet card and available on LAN.

Am I missing something?

 

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.

 

Unable to detect Ethernet cable

All of a sudden my Windows 7 computer cannot detect my ethernet cable. I’ve checked the cable, switched cables, changed router ports and nothing has worked. I need real help here. I’m trying to switch to a new Windows 10 computer and need to access One
Drive.
