I keep having trouble with my wifi and I wanted to know if anyone else has had the same problems or know any solutions. I can connect to a network the first time no problem, but if I leave that wifi then come back my phone won't connect. I have to "forget" the network then re-enter the password every time. Its annoying. Any help would be great. I'm not really able to make it to the genius bar for help for another few weeks so i'd like to be able to fix it on my own.
