So, from the command line are you still able to ping Google (or anything)? And to clarify, other machines on your network are are able to get out using the same method (wireless, assuming that the 'broken' lapper is going out via wireless). If you have a spare Ethernet cable, try plugging the lapper into your router, maybe do an "ipconfig/release" and "ipconfig/renew" just for yuks, restart IE (or Firefox), and see what happens. Also, in IE, click Tools, Internet Options, click the Connections tab, click LAN Settings, and make sure that the "Use automatic config...." and "Use a proxy server..." boxes are not checked. Again, I'm guessing that you're not running your own proxy server at home... Assuming you try all of the above and shit still ain't working, turn off the laptop, let it set for a moment, power it back on, see what happens. I know, I know, you already tried rebooting, but it's Windows. If a reboot doesn't cure it...
