I’ve noticed a definite difference in sound between wi-fi and cell calls since first moving from 2.0 to 3.0. Voice quality and volume sound great on GSM cell, but thin and at a reduced level on wi-fi. It’s much more noticeable on RW to RW wi-fi. The volume setting necessary to hear a friend who signed on with RW recently resulted in an uncomfortably loud level today when I later talked with a family member who’s on landline. Making matters worse, my Moto X Pure occasionally gets handed over to cell even when I’m sitting no more than 6 feet away from my TP-Link Archer C7 router set for max wi-fi signal levels. The sound difference is jarring.

Am I the only one experiencing this? I have no idea whether the fault is basically with my phone or the RW system. But there’s a problem somewhere. I’m pretty sure it’s not the router since the same things happened with another router.

I didn't find the right solution from the internet.
