Many users of iPad 3 and iPhone 4S complain about connection problems with the Wi-Fi and Bluetooth after installing iOS 6. The connect button is grayed out and is not activated. Some do-it-yourself remedies seems to resolve the situation: Apple is already aware of the problem.
The problem seems to affect a large number of users, in the Apple discussion forum there are more than 90 pages post reported the malfunction.
As a solution, some users have downgraded the operating system and re-installed iOS 5.1, others suggest to reinstall iOS 6 or reset the network settings. These two solutions do not seem to solve the problem for all users.
In U.S some users have shown the problem to Apple employees in the Apple Store, in some cases smartphones or tablet is replaced if it is under warranty. Other users who have contacted the support staff stated that Apple is already aware of the problem. By the time Apple has not issued an official statements on the issue.
