I bought it on CEX so its second hand, I held the reset button when you do it for 30 seconds.
When I done this the wifi on phone would show but wouldn't have any connection with it. And on the computer it wouldn't connect to internet via ethernet.
So I reset it again and now I'm back to being able to use the internet via ethernet but no Wi-Fi.
Also yes I'm watching YouTube videos as we speak so I can load other websites.
