IPhone 6 with iOS 9.3.1 won't connect to Wi-Fi unless right beside router?

I've had my iPhone 6 for over a year now, and haven't had the problem until about 2 months ago. It has absolutely nothing to do with my internet itself, because we have other devices, including other Apple devices, that work perfectly well. This doesn't only happen at my house, it happens everywhere. The Wi-Fi works perfectly as long as I'm standing right next to the router, but if I walk away, the connection goes away. It's almost like my phone can't pick up the connection when it's slightly weakened. I've reset the network settings, but it didn't work. I'm trying my best to avoid a full reset, so is there anything I can do before I try that? I'm getting super frustrated and I've almost completely used all of my cellular data.

Go to settings>general>reset>reset network settings and see if that works. It won't reset your phone it just resets the wireless antennas and clears the caches. You'll need to re-enter your Wi-Fi password after the phone restarts.

  • What's the difference between a cheap router and a good router? Just wanted to know the difference between a cheap router and an expensive router, I know that is a very broad question, I'm just a bit confused on how a router works. Does it increase my Internet speed on multiple devices? I get 50Mb per second, Well at least that's what I pay for. I have a PS3 two iPhones and a tablet, as well as a desktop PC that is wireless.
