My TP-link modem/router comes with the guest network feature; I was wondering: if I use an AP (connected via Ethernet cable + unmanaged switch to the router) to bring the WiFi to the second floor of my house, the guest network will be available there? Or will be available only the "classic" local one?
I'm asking because I prefer to not connect my gaming console and my friend's phones directly to the main network for safety reasons.
Hope to find an easy way to extend the area of the guest network to the upper floor of the house.
