If you can't even access the router then something is blocking it or the machine is having a problem.
I know you tried resetting winsock but maybe a complete reset of the TCP/ip stack would help.
Try running this batch file which will reset winsock, reset the TCP/IP stack and release renew your IP.
Tried disabling my AV software (Microsoft Security Essentials), no dice.
Ran sfc /scannow, nothing abnormal detected.
All IPv4 settings are set to auto and default.
Thanks very much for the help so far--it's already accomplished 5x more steps than FiOS could ever drum up.
You might want to check in services.msc to make sure all the networking services are running.
Also check the Advanced sharing settings because they have been known to change for no reason.
I havn't seen a problem quite like this one, normally when this happens the default gateway IP isn't showing up.
Have you tried typing in the routers default gateway into your IPv4 properties? That will sometimes get you around a router problem. It's acting like the cable is bad or something but you said you tried using another cable....
Now the Connection status keeps wavering between no network access to no internet access. Like every 3 seconds it will switch. 286k bytes received and 0 sent. hmmm...
Now it works. I insulted it enough times I guess that it caved.
Unbelievable.
Thanks for all the help everyone, I don't think anything actually did anything, it just had a will of its own, but now i know what to try next time.
