I have Ubuntu 12.10 on Toshiba Satellite P745-S4102 and after I click on a wireless network it says "connection established". Then if I go into Firefox or Chrome and try to access a web page it says "server not found". I have it partitioned from Windows 7 and the W7 WiFi works fine. Ethernet also works fine on Ubuntu. I've looked through a bunch of different threads and can't find a solution that will work. I am very new to linux so please bear with me.
