@Carl Unfortunately my new wifi setup is 2 x XE75 Pro and 1 XE75. If I'm returning gear, it will all go back. I have a temporary workaround for the IOT issue - i'm using my old ASUS routers as APs...

@Carl Switching channels breaks connectivity for some smart devices (Wyze cameras in particular). We need an IOT setting for 2.4ghz where the channel selection is locked.
