My WiFi has flopped all of a sudden I tried to connect to the Internet with my cellular phone it also it did not connect, after sometime it did connect on it is own. This has happened to me number of times over the past 2 months. Is it hardware issue or an issue related to operating system. The nearest service centre is 500 kms away from the place where I live. WiFi does not get recognized. Kindly help me, Narayanan Lakshmanan from India

You’ll need to get a bit more diagnostic info to figure out whats happening. Go to the Apple store and get WiFi Explorer Lite so you can see your WiFi network as well as competing networks. You may need to manually set your WiFi network to a different band as the one you are using maybe congested by others.
