I am trying to get a network setup in a small condo building. For multiple reasons, running cat6 is not a very good option. As a result, I am trying to find a way to get 4 separate wifi networks setup, each with its own password, without running any cable. To add to the complication, the signal from the main router, which has to be in the basement, does not carry very well two floors up to the top unit. So having separate access points that simply go back to the main router is not really an option. Would something like the attached drawing work? I am thinking of using the NETGEAR AC1200 as the range extender and TP-Link AC1200 for the access points.
