Okay so the other day I got my laptop for college and it came with Windows XP on it. Well today I decided to upgrade it to vista business 64 bit which also came with the laptop. Well before I could easily connect to our wireless internet but now with vista installed it's like the computer doesn't pick up ANY wireless signals. It says install networking hardware, and verify that the correct drivers are loaded. When you do the Windows Network Diagnostics. I even pluged in an ethernet cable and it still won't connect to the internet? What did I do to my computer?
