I have a RFS4000 controller connected to a dozen BR650 WAPs. The Controller is running firmware version 5.3.1. Recently it was brought to my attention that many of our Linux users are experiencing random disconnects. Some multiple times a day and others just once. None of our Mac OS users are having any problems. In fact, I run Mac OS on the wireless network constantly and I have never had a disconnect. Windows machines (the few we have) seem to be just fine as well.
We have tested multiple SSIDs and the problem persists across each of them and different radios.
The logs are showing users disconnecting because they are roaming but they are not moving during the disconnects.
I've attached a file containing the log output for a single user, who experiences the problem quite a bit.
Any help or suggestions would be greatly appreciated.

Hello davidengel. I took a look at the logs from the client machine and all I can gather is its lists 'what' is happening, but isn't detailed enough to really know why. For example, Reason code 15 shows the 4-way challenge handshake timed out (but cant identify the cause). Also, this particular client was disassociated (reason code 14), but also cant determine root cause from the logs. All I can suggest at this point, if you feel this is being caused by the Brocade RFS controller and/or 650 AP, give support a call and open a ticket.

You're welcome. Would love to hear what the cause was on this if you care to share when its all said and done.

It seems like the issue was resolved by simply upgrading to the latest version of firmware. Currently running 18.104.22.168-020R. I am actually wondering if it was the reboot or the firmware update that actually fixed the issue? Support was silent on what the cause was, but hey, it's all fixed now.
