When trying to add a device it constently looks for an IP address and can take 5 - 45mins to get one.

Most of my devices connect or disconnect too!

i have latest firmwear,( but was happening on old Firmwear.)

ITs with Apple products, TP-link smart light / plugs, Samsung TV / fridge, HIsence Tv's

have contacted support and run out of things to try so been esculated to Engineer of which ive waited 2 weeks to hear from !

devices plugged in by cable ( this Mac studio) are fine.

Have tried to add to IoT network and things are the same!
