iPhone won't connect to WiFi

My iPhone won't log onto my home or work WiFi. It recognizes them and I have put in the correct passwords but I just get an alert saying "Unable to join the network...".

I can't find any info on this. Any clues?

The phone connects via 3G

PowerBook G4, iPhone

Oh, I didn't know about ad hoc being tempermental. Thank you for this info! 🙂 Since I last wrote, I was perusing my FB page and a friend of mine posted that she has a router to give away, and would anyone want it. 😎 Very cool. Sooo, it looks like tomorrow, I will have a Linksys by Cisco, model WRT320N-RM. I called her and she said that it works fine. They've been running multiple Macs, and streaming Netflix without any problems. They purchased a Tivo, and noticed that the addition is too much for the router to handle, so they upgraded to a dual-channel router. Synchronicity!!

Still not able to connect to wifi anywhere, Safeway, Starbucks, etc and of course home, all apps work but not connected to wifi, so therefore it will be charged to my airtime on my iPhone cell bill. Only connects if I plug it directly to my computer


If you can't connect to WiFi anywhere, first try Settings/General/Reset - Reset Network Settings. If that does not resolve the problem see: http://support.apple.com/kb/TS1559. If none of those instructions solve the problem your phone is broken, and you will have to get it replaced by Apple. If it is in warranty it will not cost anything.
