Hi there, I am having getting poor wifi coverage on the opposite side of the house where the NBN modem is connected. I'm thinking about buying a Google Nest wifi to replace the provided TP-Link AC1600 router. But I have been reading that the google nest isn't compatible with the Arris CM8200 modem I have.   I would like to know what wifi routers I can buy that are compatible with the Arris CM8200.   thank you ...
