Some users of the iPhone 4S and third-generation iPad are reporting ongoing wireless connectivity problems after upgrading to iOS 6, according to a thread on Apple's support forums. People may, for instance, find the option to connect to Wi-Fi grayed out. Others may be able to turn Wi-Fi on under Settings, but nevertheless be unable to connect to their LAN. Still another group is experiencing trouble with Bluetooth, which may not be able to detect or pair with devices, simply scanning for them forever.
