@TP-Link I had two networks, both named WiFi. One with the old M5 units, and one with the new X60 units. I chose the WiFi containing the M5 and chose delete, and gone were both of them. I'm guessing...

@Tony.Broekhof It will remove both.... Having just done it, in an attempt to remove the extra/old wifi, I am now stuck without any internet and all settings are gone........
