I own 3 of these. One setup as a controller which can also broadcast. They support fast roaming so that I maintain WiFi throughout a roam between APs. A little tricky to setup but there are guides on the net. The built in wizard helps a bit. Forget using consumer APs and routers and get pro gear.

Amazing product with easy setup and management console... I work with many wireless access points. Edimax WAP1750 provides me the best speed and range. There is an extra LAN port for another PoE device.Highly recommend it over other AP's which I have tired in the past.
