I am currently connected to my school's network. It is protected with WPA-PSK. I got a weird problem with it. Internet works on Firefox but doesn't not work on IE. Asking win7 to fix it will not help. I will ethier say the problem is fixed( in reality, it is not fixed) or it can't find any problems with the network. I can't sign in to my windows live as well. Clicking troubleshoot gives a "key port" error. The gatewway is a govern by a software called sonicwall. Vista or XP doesn't not have this problem. I can do basic diagnostics but i don't know where to start.
