Here's an odd one. I can connect to the internet if I go Network->Network and Sharing Center->Set up a Connection or Network->Connect to the Internet, and it tells me I'm already connected to the internet, so it asks me if I want to browse, and I choose "yes", and it connects me to the internet, but I still can't connect using my Firefox or IE shortcuts.
Also, if I try to connect to a Call of Duty 4 multiplayer game it says it goes through all the available servers like it normally does, but it doesn't display those. The same thing happens with Outlook, I can choose to send and recieve my mail, and the window pops up, but closes immediately, no error message or anything.

I'm lost and confused.
