I cannot turn on Wi-Fi on my iPhone 4S

I've tried all of the above....

My Mac Air and iPad are connected to my house Wi-Fi.

4S device has connected before.

I've reset the device and the network settings.

I select Settings>Wi-Fi> and the Wi-Fi button is greyed out and will not turn on. This is also the case when in range of another hotspot.
