So I've had no problems with my wifi before. Now I'm trying to connect to a network but it does not work. Basically I go to setting and click the network, and everything seems normal. The wifi bars show up on the top. Then when I go to safari the screen turns gray with the word "connecting..." in the middle and a spinning wheel. Also when I click on the blue arrow next the network name, the only thing that shows up are the IP address and the subnet mask. Everything else is blank. Does anyone know what the problem could be? I am jailbroken running on 3.0.1.
