Just bought a new computer for grad school, but I can't get it to work with the wireless in my house. It'll connect (with limited connectivity), but won't do anything beyond that -- the web won't work, email, etc. My ipad and phone connect just fine. I successfully used the wireless while at my parent's house a few weeks ago, though it didn't have much range. Any ideas?

I've rebooted the computer. I haven't been able to reboot the router because it is in my neighbor's place (I live in a duplex). I plan on trying to reinstall the wirelesss driver once I get to school tomorrow.
