my computer rejects any incoming wired connection ... why?

Question

yesterday i noticed the internet connection suddenly not working. it said "a network cable was unplugged" even though the ethernet cable was plugged into the computer like it always is.

so i tried restarting the router, restarting my computer, unplugging the cables, all the standard quick fixes. none of them worked. but what DID work was when i plugged in my roommate's ethernet cable into my computer. i had working internet for about 5 minutes, then it too stopped working. then i switched back to my normal cable. it worked for about 5 minutes.

the reason i'm able to post this question is because i'm alternating between my cable and my roommate's cable every few minutes. it's incredibly annoying and i can't function like this. but more importantly it shows that the problem is not the router or the cable -- my roommate's wired connection runs fine -- but rather a problem with my computer. for whatever reason it simply doesn't want to be connected to any wired network. i've disabled firewall and my anti-virus software and i've updated all my drivers.

i have an ASUS G60s gaming laptop, and i've had this problem before. after a few days it went away by itself. but i have a research paper due tomorrow so i don't have time for such a break. is there anything else i can do?

Answer 1

Check the laptop power saving modes, you may be turning off the network adapter after 5 minutes.... You may have different settings while on AC power vs on battery power....

Answer 2

Don't know if you are on a laptop or desktop. But to get over the hump, I would buy a

usb ethernet adapter OR swap out that ethernet card. I guess you could check to

see if something is flooding the card with packets, which would make the card

reset with the process of unplugging the cable.

Answer 3

check windows update for a new driver. if there is none it means: your ethernet port is screwed, which means your computer is screwed.
