We just moved into a new house. I have the nest wifi that I used in my old house, but this house has Cat 5 wired to every room so I am thinking of doing some wired access points. I know I can use the nest wifi to do this but there is one use case that I can't solve.

The basement is a rental apartment, and I want to provide a feed to them through cat 5 and then let them figure out their own router. Preferably I don't want to give them access to my network.

What are my options?
