I have a 750M that works great. It can connect to the internet via other routers and other devices can connect to it and get internet access that way.
I have a Wyze Cam that I can use on lots of other routers. I cannot get the Wyze to set up on the 750M. Wyze support says they think there is some sort of “Client Isolation” enabled on the 750M, but I cannot find anything like that in settings or advanced settings.
