If it's not one thing it's another.... This is not an uncommon issue, but I have not found a solution despite trying everything I've read. I have two computers, an iPad, and an Apple TV that have not trouble connecting to my home network. WPA 2 Personal via linksys b/g/n router. No issues anywhere in the house. But now my iPhone 4 refuses to join the network. I get the "Unable to join the network xxxx" message. I've tried Airplane mode + wifi on Resetting the router Switching to WEP and then back to WPA 2 Forgetting the network and re-entering the password Restoring the phone Etc... Basically the phone just won't join. Period. I have noticed one tell-tale little detail: When you enter the password to a network the "join" button does not light up until you enter the correct number of characters. When I am entering what I absolutely know to be the correct password, the "join" button lights up two characters too early. WHAT THE FRAK IS GOING ON HERE? This is the correct network....the correct password....the correct settings.....everything is right. But the phone refuses to connect. Anyone have another idea?
