So I just got an Ipod touch, jailbroken, 1.1.2. The wifi worked fine all night yesterday, and today morning as well. However, out of no where, the wifi started dancing in and out. It connects, but doesn't do anything. The bars keep coming and going. I'm pretty sure it is not a range problem, because I am sitting 2 feet from my wireless access point. I know for a fact that I also supplied the correct WPA key. What I really don't understand is how something that was working absolutely fine starts behaving like this. Has anyone ever experienced this before? I would greatly appreciate any feedback. Thanks.
