I installed a Cisco Aironet 1200 access point for use with a few Macs, some old Dell D600 and iPhones. I have enabled both G and A netorks (tried various channels as well) and cannot get the old Dell D600 and/or iPhones (3G and 3GS) to see the network. The Macs and my printers see it perfectly. Any suggestions?
I'm having a similar issue, iPhones connect to the broadcasting open SSID but not stay connected to the hidden simple WEP 128bit network. I've even tried a WPA2 network but iPhones won't stay authenticated to it either, and it was broadcasting. Using 1200 with same IOS version, going to try latest IOS today and see.
I installed IOS version c1200-k9w7-tar.123-8.JED and iPhones with version 3.0 work fine, but 3.0 and up still do not, but I turned off broadcasting on my public SSID and they all work now. This is just a temporary solution for now, but I think helps troubleshoot the problem.
