Windows 10: Computer reads ethernet cable as "disconnected"

My ethernet has recently been turning off and on, in a matter of seconds. One second it'll be off then a moment later it will turn back on. I've tried everything, hoping I can find some sort of fix here.

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 disconnected

my laptop's ethernet adapter show the cable to be disconnected while it is actually plugged in. Moreover the cable doesn't lit-up now as it used to be when connected to the laptop.

 

Windows 10 restart if ethernet cable is disconnected

Windows 10 shuts down if the Ethernet cable is disconnected. Computer will restart but shuts down again (in a minute or two) if the Ethernet cable is not connected. I cannot go wireless
