Um, bandwidth limiting? As long as the AP has the upload speed coming from the client capped to a rate slightly less than the total capacity of the pipe, its not a problem. I'm doing the test right now, and I have rock solid pings, with a little bit of jitter. > > What we really need is the Nanostation-ROS... a Nanostation running > Mikrotik (even for $50 more per unit)... that would be the killer > CPE...
