Unknown Ethernet Controller

I turned my computer on today and my internet wasn't working. I went into
the device manager and see that the ethernet controller is listed under the
unknown category for some reason. I don't know why. I have removed it and
tried to reinstall the drivers over and over again and it keeps going to the
unknown category. This just happened randomly. I can't think of any logical
reason. The only error message is "error 31". Can someone please help me
out. Thank you.

Maybe the card just failed. I've had two ethernet cards burn out in
11 months once. I switched to a different manufacturer and it was
still running after two years.

Hardware does fail, after all!
 
Well, its an onboard ethernet controller. Has anyone ever had one of these
burn out? If it is burned out, why is Windows even recognizing it???
 
Hi,

Just for your reference, it could happen in some cases when driver and its
associated registry files are corrupted.

To see if it's the problem of onboard controller, you can go to BIOS
settings and go to section similar to - Onboard device or controller, and to
see if the onboard LAN is being turned on or off.

If it's off, it might be the problem. If you experience the same problem
and are sure it's being turned on, turn it to OFF and shut down the system
and place another network card (with driver ready) and see if the new NIC
works. If it works fine, it is likely your onboard controller does have
problem. You would have to contact MB vendor for onboard controller problem.

Although many newer onboard Ethernet controllers do not need drivers, you
could still go to MB vendor's site to see if there is (new) driver available
for download. If so, download and install it and see it make any
differences.

One of my systems uses Asus P4P800 SE which comes with Marvell Yukon Gigabit
Ethernet Controller. To my surprise, the drive update was coming from
Windows Update. So you may want to run Windows Update as well and see if
there are any updates.

Hope this helps.

Try bottom posting instead of top posting; it makes the thread easier
to follow.

As to your question, yes, I have seen many onboard NICs burn out over
the years. Yes, I have seen Windows still know that something was
there, but not able to use it. Yes, the system worked fine when we
installed a new NIC into a PCI slot and returned the system to
service.
