I'm having the same problem. I have 7 MSM-466 AP's tied into a 720 controller. The download speed is what it should be via the wireless connection, however, the upload is horrible. We're running a symmetrical 30mb fiber connection as the last mile provider, and when we run a speed test on speedtest.net, we're able to get close to 30m down, but we're not even hitting .5m up. As these tests have been run, we have bypassed our RADIUS authentication, so the RADIUS provided bandwidth limits are not going into place (even if they were, we have them set at 7500kbps). The laptops we are testing this from all have excellent signal strength and show an SNR of 30 or higher on the radio they are connected to. We're using 15dbi sector antennas on the 2.4 Ghz band. Sectors are 2-pole antennas. The third port on the radio is capped with a terminator. Built a very similar network...Almost identical in fact, last year, the only difference is that it was running on a 710 controller. Both that 710 and this 720 are running firmware version 5.7.3.0-sr2 and the access points are all in controlled mode. Any ideas or thoughts on this would be greatly appreciated.
