Can't Join Time Capsule Network after ...

Hi,

I have a Time Capsule (TC) that broadcasts my Wifi dual-band. I also have it configured to offer a guest network as well. After updating my iPhone 3G to OS 3.1 over the weekend, I cannot join my main TC network, but I can join the guest network (?!).

I can see both networks in the Wifi settings on the iPhone. I restarted the iPhone holding down the home button and the top button, but no luck. Next, I tried forgetting the main network, rejoined it and reentered the WPA2 passcode. I was still unable to join. At that point, I had the iPhone join the guest network with no issues.

Ideas? Thanks for any feedback. This forum is collectively so helpful. I have answered hundreds of questions by browsing existing posts. This is one of the few times I felt it was necessary to post my specific issue.

Best Regards,
