Typical house with a basement, there are about 4-5 renters.
There is a Cat6 line going from my main router to downstairs, which is then connected to a signal booster to give them all wifi.
I’d like to keep the renters completely seperated from my main house home network.
How do I seperate the signal booster/renters from seeing any devices on my main house router?
Should I connect a switch or router in between my main router and the signal booster?
As u/Mannus01 mentioned, using the guest network, with client isolation is the easiest way, as it is only a few clicks in your router settings.
However, that might also limit what your renters can do with their network. For example, if they have a WiFi printer, they wouldn’t be able to use it, since the clients are fully isolated from each other.
Using two routers would isolate ONE of the two networks. . . but in order for them not to be able to see your stuff, they’d have to be the first router – the one connected to your ISP. Your router would need to be connected to theirs. . . which could cause some connectivity issues for your stuff. (Gaming, etc.)
Without getting their own ISP, the only way to give your renters the same networking experience that you currently enjoy would be to use a more advanced router that supports VLANs. Then you can keep your stuff on one VLAN, and theirs can exist on the other, with each one having access to the internet, but fully isolated from one-another.
