Iphone 5 not connecting to home Wi-Fi? - 1

My iphone used to always connect to my home Wi-Fi but it suddenly stopped working, It connects to all other Wi-Fi apart from my home Wi-Fi, it connects to the network but the loafing symbol keeps spinning and won't connect me to the internet.
I have tried forgetting the network, resetting network settings, using the static option, trying to connect using 'other'. None of these worked and I rebooted my router and it worked for about 2 hours then I lost the Wi-Fi suddenlyagain.

What could I do to try and make it connect again?

Change your protocol to PPPOE
