I have a Deco X4300 mesh home network. It works great except for one major item. WiFi calling does not appear to work. Dropped calls and distorted audio is common. We have Samsung S22+ phones. Spectru

What is the difference between Deco X60 and X5000? The comparison pages show none.

The web portal cannot find the powerline extender, but I am able to connect via the utility. Unfortunately the utility doesn't seem to offer control over the channels selection. How do I change them?
