My iPhone 5s suddenly began to have poor wifi reception. I basically have to be right next to the router to use the wifi, and it happened all of a sudden the other day, before that it was getting wifi signal throughout the whole house. It's the same in another building we have with a completely different wifi connection, it doesn't work unless I'm within a couple yards of the router. All our other devices work fine, so it's not the connection or the router, it's my iPhone. I've tried rebooting, hard rebooting, resetting the network settings, and nothing works. Do I need to get my iPhone replaced to get this resolved? I bought my phone in November, and just had to get a refurbished replacement from Verizon back in February or something, because it wouldn't get phone service where we live.
