Replaced battery without incident. WiFi now works poorly at home, but continues to work just fine at work and elsewhere. Not that WiFI signal is weak, rather the phone does not even find the home network unless I am standing right on top of the box. Cellular signal is intact everywhere. Tried turning phone off; tried hard reset; nothing seems to help.
Hi there, This could be an issue with the wifi antenna that is located near the battery. I’d double check that it is seated properly in its socket. After that turn your phone back on and test. Thanks
