If you've also tried a complete factory reset and it did not help, bring it to an Apple Store for hardware diagnostics.
Phone has already had good WiFi signal everywhere in my house.last few weeks it is nit existent far away from the router and much weaker when I’m in room with router. Done all resets and problem persists.is it just because the iPhone is now 3 and a half years old and I need a new handset?
