Tried Single modes G and N - no good
Tried Mixed G/N - no goodChannel Width set for Auto 20/40Mhz or try 20Mhz only.

Tried 1, 6, 11. No difference.What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto.
It's set to: Auto (WPA or WPA2) + AESThe devices have profiles and should be checked to see if they are set up to remember last connections as well. My iPhone 4S remembers the last connected signal. iPhone running iOS v6.1.2
