My customer is using a thin client application over wireless. The thin client keeps locking up and they have to reboot the client to recover.
I do not believe this has anything to do with the wireless LAN infrastructure but I wanted to see if anyone has seen this in another environment and what may have been done to resolve the problem. One thing that we did find was that when pinging from the thin client to any other device, including even it's own default gateway, the response time can vary from a few ms to over 1000 ms. Eventually the client timeout gets hit and the client locks up, requiring a reset to recover. However, when I associate to the same SSID and I am connected to the same AP as the clients we tested with, I do not see this problem. Again, this leads me to believe that the issue is on the thin client/application side.
If anyone has any experience with this client or is aware of any parameters we could tune on the WLC end, I would welcome any input. We have confirmed that the timeout value for the client is set for 3 seconds, which is the maximum timeout vlaue. Additional details are below.
