iphone 6 drops wifi signal
Hi,
I've had my phone since September and haven't had a problem with it until now.
I can connect to my wifi router when I'm in the same room, but as soon as I leave it drops connection and I can't find the router when searching.
I know it's not the router as all my other devices connect and I can't connect when I'm round other peoples homes.
My laptop is broke so I can't restore my phone using iTunes.
Any ideas what I can do? or should I just give up and get it repaired under warranty?
iPhone 6, iOS 8.3, I'm on Virgin mobile as is my wifi
