Just posting this info incase anyone else has any problems with wifi. So when you search for your router and enter the password it should store it so it's remembered. Mine would not do this so if I went out or range the password would have to be re-entered. I've never had that so it must be a bug.
What i did was manually enter the router name and password in the 'other' section on the wifi settings and now it works perfectly!
