Sorry. I should have explained it better. We have an apartment block with 72 apartment, each with one cat 5 broadband point from a central internet connection. We are looking at using wifi routers in each apartment, if feasible, and manage - monitor these routers, as or if required, with the Tether app. I was unsure how many routers  the tether app would support.

@Kevin_Z  Yes, I know exactly what you mean, its not ideal, a web base version ot Tether is needed. I could use access points, but a/ I don't have POE on the switches, b/ I need desktop units, as apartments are privately owned, and we do not want to mount or ceiling. c/ Its almost impossible to schedule or coordinate an install of access points due to the fact they are in constant occupancy holiday let, where as the router, cleaning can place on the desk, and plug it in.  d/ Client segregation. f/ I need Mesh in larger apartments, and again, not possible to install cabling, has to be WiFi mesh .g/ some form of login security. Its a dilemma.All suggestions welcome.
