iPhone 3GS won't connect to Airport Express Network despite other 3GS and 4S iPhones connecting fine
We have a household with 3 iPhone 3GS, 1 iPhone 4S, iPad, MacBook, 3 Windows PCs. All can usually connect to the Airport Express WiFi network. However recently one iPhone 3GS phone stoped being able to connect to the Airport Express network.
We tried resetting the iPhone 3GS to factory settings and this did not fix the issue. We eventually had the phone replaced under the insurance I have with our cellular provider.
Now the same iPhone has just started doing exactly the same thing again.
The symptoms are that the iPhone 3GS, sees the Airport Express network, it requests the password. The user enters the password and the little radial spoked wheel rotates endlessly and the iPhone 3GS does not connect to the network. Now the WiFi IS working as I have a 3G/WiFi bridge on test called a WiBE and the phone in question CAN connect to this using WPA/WPA2.
I have rebooted the Airport Extreme and the Airport Express network extenders several times as well as the phone, but it does not make any difference. This iPhone 3GS does not like the Airport Extreme network.
I cannot believe I have a second faulty handset weeks after we had it replaced. Anyway it is not faulty as it successfully connects to a different WiFi network without difficulty.
What is going on here?
Any ideas chaps?
Thanks for any comments
