Yes, it is possible. But it depends on how many users and routers you'll have, how much bandwidth you'll be using and how much money you want to spend on this.

Radius based solution.

  • You may buy routers with radius authentication. (e.g. Mikrotik, Ubiquiti)
  • Or use unofficial firmware for standard SOHO routers (e.g. DD-WRT, OpenWRT)
