I have 1 iMac, 2 iPhones and 1 iPad. All of them connect to the Internet using the same wi-fi network.
Suddenly, all, except iMac, lost connection. They still can be connected using 3G.
iPhone 5, iPad, iOS 6
What is generating the WiFi?
I have installed a router through which I receive wirelessly internet.
In the mean time, I unpluged the router. Counted 1 to 10. Pluged the router again. Problem solved.
I still don't understand why iMac operated wirelesly all the time without problem.
Anyway, thanks for your time.
