In my home I have 2 available WiFi connections. My neighbor's and my own. I use my own but sometimes when I don't have my internet on I would use my neighbors. So today I was connected to my neighbor's internet but yet none of the apps like Facebook and AIM that require WiFi would work. Safari wouldn't load either. But on the top I still see the WiFi bars and it shows 2 bars. I tried to connect to my own internet but after a while it said "Unable to join the network <network name>" Neither internet connection works but there are still WiFi bars. Why is this so? How do I fix this? If it helps, I'm on a jailbroken 3.1.2 iPod touch 2nd generation.
