I recognize these problems. We have around 60 UL networks and run the 200.6.xxx software on 3 of them. Clients have frequent disconnect problems without any reason. I reconfigured the networks to the most basic state and it works more ore less now. So no background scanning, fixed channels and throughput limitations. On other networks we encounter no such problems so we suspect the 200.6 software. Recent experiences show that Ruckus often need multiple versions before they run smoothly.
