Since I reinstalled windows 7 ultimate x64, my computer can not see the ethernet cable. Now I use wifi stick, but it's so slow.

I have tried:
-downloading realtek ethernet drivers
-putting into another slot in the router
-I tried to do something in the BIOS, and there was something called SMART lan, and it recognized the cable.

I noticed that there is no light where I plug the LAN cable in the back of the computer.

Any ideas? Thanks.

Check if the device is working in Control Panel, Device manager

Did you install the new drivers? (Not just download)

It literally says "windows doesnt work well"?

What about looking in Device Manager and finding the ethernet device under Network Adapters and then checking if it says its working?

Code 31 - Windows cant load the drivers.

Make sure you've got the right drivers for your windows. Get it from your motherboard website or the realtek website for that chip.
