I have wifi blackspots in my house and my current wifi extender is not working as expected. I would like to get a wifi mesh (such as the TPLink M5) but need one that is compatible with my NBN Modem.
Welcome to the Community!
The NBN modem/router that we are providing doesn't have any restrictions to the devices that you want to connect to it, especially mesh or extender devices.
It should work for any kind of WiFi mesh or extender technology.
