I have several Parks with the XV2-2T0 and XV2-2T1’s. Running 6.6.0.2r5, They all suffered form QOS errors causing frequent dropped connections and erratic roaming. I had to revert back to the 6.5.3r8 to correct this issue and provide a stable Wireless experience for the users. Does this new 6.6.0.3 fix this QOS problem.
