I have two Apple devices which flat out refuse to connect to our company WiFi, an iPhone 5 and a 'new iPad' (3rd gen). Both are running iOS 6. The iPad could connect while it was on iOS 5, but not since upgrading to iOS 6. When selecting the network, I'm prompted for the password, but once I've entered it (correctly) I get the message 'Unable to join the network "network name"'.
The company WiFi is run on Netgear WAG102 routers, using WPA2. My previous iPhone 4 had no trouble connecting even while running iOS 6. My room mate's iPhone 4S is connecting fine, though it's on iOS 5 still.
Any ideas what might be causing this? What can I do to troubleshoot and solve the problem?
