Wifi works, but only if right next to the router
My phone will show full bars for the wifi signal, but won't connect to the wifi or load pages unless i am in the same room as the router. My wife has the exact same phone as me and my son has the 5s and neither of them have this problem. This is not limited to my house's router. I have the same issue at my in-laws house.
The only thing that i can figure is that the strength of what my phone sends to the wifi router is very weak. It works just fine if i am standing beside the router.
Any ideas or should i drive 45 minutes to the genius bar to get it replaced? Thanks.
