Thought I'd jump in this one, sorry if I'm late to the game, I'm a Meru customer and you do not have to have all the aps on the controller broadcasting the same speeds. Broadcast speeds are set in the ESSID section (virtual Cell). I have virtual Cells on campus that have B disabled and the slow speeds of G disabled, while I have other Cells that have all speeds enabled for all 802.11 protocols. All our access points terminate at a single controller. Best,
