I recently purchased an iPhone 4s (upgraded from my 3G). Try as I might, I can't get it to join my main home wi-fi network. I never had any trouble conencting with my 3G. The 4s connects easily to other wi-fi networks; I've had no other trouble with the 4s. I have installed the most recent 5.0.1 iOS update without trouble.
I have an AirPort Extreme third generation (3 years old), and have also updated it to the most current firmware. I have the Airport configured so there's a main home network and a guest network.
Oddly, the 4s can join the guest network without a problem, but when I try to join my home network, the phone tells me I have either entered the wrong password, or that it simply "cannot join" the home network.
I am using WPA2 Personal security settings, and have let the Airport configure itself automatically. I haven't set anything manually in terms of channel, etc.
I have changed the password to my home network, thinking maybe I had it wrong, and I get the same messages on my iPhone 4s: unable to join network, or incorrect password. I am sure I am typing the password correctly.
I can connect to the home network via my MacBook without any problems. Connectivity to the web works fine.
So. I have walked through all the trouble-shooting ideas I've found on Apple's website to no avail. I've spoken to two Express Lane advisors, who gave me other tricks to try that have not fixed the problem. Now they advise that I simply restore the phone, but I am reticent to do so before asking questions here.
Does anyone on this forum have any ideas for me, or is it time to do a restore?
Please let me know if there's any other information you might need; I am new posting here, and not an IT professional (or even very familiar with Mac equipment).
Thanks for any help you might be able to offer.
