My phone is the only device that has a bad wifi connection
My iPhone 6's wifi connection was working perfectly fine until about 2 months ago. Now, 5 feet is about the maximum distance i can be from my router in order to get a connection on this device. Every other device (iphone 4, ipad, tablets, laptops) has a good connection throughout the house. Another thing I should probably note is that my phone has a great connection to other spots such as public wifi and personal hotspots. And also that my phone has not had a SIM card for the past 7 or so months.
This is what I have tried:
-Factory reset on phone
-Reset Network settings on phone
-Disabling bluetooth on phone
-Disabling "wifi networking" under phone settings-->privacy-->location services-->wifi networking
-Switching dns to ( 220.127.116.11 ) , ( 18.104.22.168) , and ( 22.214.171.124,126.96.36.199 )
-Renewing Lease through phone
-Switching Channels through router settings
Is this a good question?
