Networks not connecting; Invalid IP configuration with every network I attempt to connect with, wired or wireless

I've been having a problem with a newly-upgraded computer (Vista to Windows 7)... The net wasn't working just before I upgraded it to 7 (I had uninstalled Norton on request from the upgrade advisor or whatever as well, that might be a factor). Every network I attempt to connect to has an invalid IP configuration. I've tried the netsh commands, but that didn't work. I've installed an updated version of my networking driver (Nvidia NForce), still no. I've tried manually assinging IP addresses, but still no. Both networks I have connected to also show up as unidentified. The laptop I'm using to put this question up, my PSP, my 3DS, and the PS3 all can connect just fine.
My IPConfig is:

If anyone could help, it would be -greatly- appreciated, I used to do a lot of things on the internet before I upgraded this old Vista to 7, and I would like to resume doing so.
