My Win 7 desktop computer sporadically loses internet connectivity for hours at a time every 1-2 days, while wifi continues working fine. I think there's something wrong with the software that drives my Ethernet card. Can you help me fix it?
The Window troubleshooter says "An Ethernet cable is not properly plugged in or might be broken," and the light on the modem that indicates an Ethernet cable is attached is off. But I've tried three different cables, and besides, after a number of hours the connection will be restored, without my doing anything. I have tried resetting the modem and restarting the computer, but that didn't help.
I think it is the software that drives my Ethernet card, because I had a computer shop install a new graphics card for me just before my troubles began. While I watched, the tech went through and deleted all the NVIDIA programs (apparently without looking at them), because my old graphics card was an NVIDIA. It turns out my Ethernet card is an NVIDIA also, so I'm guessing now that something may have been deleted that the Ethernet card needed to function.
Device Manager says my Ethernet card is working properly. I updated the drivers (while the internet was working) -- but that did not solve my problem. I rolled back the drivers -- and that did not solve my problem either. Does my Ethernet card need some software besides the drivers to function? How would I find out what that was? Or can drivers be messed up somehow, but not be fixed by Device Manager -- I would need to manually install the drivers? This is problematic, because I went to the NVIDIA drivers page
, but could not find the drivers for my card.
My Ethernet card is an NVIDIA nForce 10/100/1000 Mbps Ethernet.
What do you think -- is my diagnosis plausible? Is there something else it could be? Thanks for any advice you can give me.
