Hello, Recently my ethernet connection on my PC just stopped working randomly. I have Charter cable hooked up to a Netgear WGR614 (v8) router. Connected to the router is a Vonage box and my PC. The wireless connection coming from my router works perfectly, but the ethernet is not working. I tried bypassing the router by hooking my PC up directly to the cable modem, to no avail. I figure its something wrong with my computer. Help!
Thanks!

Connecting the PC directly to the modem was a good test. Do it again and run ipconfig /all
and do it while the PC is connected to the router. Post both outputs here if you don't understand them.Disable the wireless adapter temporarily while you test.
Actually, before you do anything, look at the device manager for hardware conflicts.
When I ran ipconfig, both tests showed that I had an IP, etc. So I know that there is a connection, but nothing works when I try to connect to a webpage or access the internet in any form. There are no hardware conflicts or anything like that, especially since this problem came out of the blue.
They weren't AIPA IP addresses, were they?
169.254.x.x?That can fool you.
No, they seem like regular IPs
Did they match the subnet of the router?
hey there ... I had a similar problem, but my computer shows no connection via ethernet at all. I tested with three cables, one known good, to no avail. An ethernet connection directly to the cable modem failed. I installed the USB driver for the cable modem to get back online, but broke the wireless in the process. ipconfig shows a real ip address for the modem via usb (of course or i wouldn't be here ;-) ) but claims the ethernet is disconnected. I would prefer to have the old setup working ... computer to router via ethernet, but I'd be fine with the USB connection if the wireless were working. I'd play around with the wireless configuration except of course I can't actually get into the thing now that the ethernet connection isn't alive.
Windows live claimed it found a backdoor and some other crap; the malicious software removal tool claimed it dug out a worm, if that has anything to do with it....
You have to clean the machine first. Then you can correct the other networking problems. Update all your virus and spyware scanners and run them. Run Hijack This to make sure they did their job, then return to the NIC problems.
