@Carl Thanks for getting back to me. Yes I have tried power cycling the M5s. Happy to do a remote session - early in the UK morning would be best - anytime between 22:00 PM - 01:00 AM Pacific.

@Carl @fatmikeATL I've had the same issue since I applied a firmware upgrade: https://community.tp-link.com/us/home/forum/topic/203838 Perhaps it is nothing to do with the firmware but just that it...

So I have a mixed network of Deco M5 units and Deco M9s. The main Deco is one of the M9s on the ground floor, on the first floor I have another M9, and then in the attic I have an M5. For a long time...
