We're having frequent roaming and disconnect issues with Apple products, so far Ruckus support hasn't been very helpful or insightful. I've recently tested ofdm-only, but it doesn't seem to be a silver bullet.
I've got R710s almost at min tx power due to the density of our deployment and limitations of the building's design (i.e. one main floor with Mezzanine levels above some areas...cinderblock walls, concrete floors, etc.)
This summer we are installing a brand new Ruckus network with 400 R710 and two virtual controllers. We have a lot of Apple devices and am interested in seeing the outcome of this. Roaming and disconnect issue have me worried. We also have a lot of Win7 machines and Chromebooks, and iOS devices. Are you seeing roaming and disconnect issues with these devices as well?
