Clients Bouncing from One AP to another

[collrbbrt]

Hello team, I have Cisco Aironet 3500 Access Points  running software version 8.5.151.0 and AP model AIR-CAP3502I-A-K9. I see clients experiencing intermittent Wi-Fi connectivity. when I check in Prime I see clients bouncing from one AP to another in just a few minutes even though the client is stationed in one location. This is happening at Random. Any clues are welcome.

Are these Windows-based wireless clients?

They are Android based scanners.

Post the complete output to the command "sh client detail <MAC_ADDRESS>".

Hi,

Please check whether the fast roaming option on the respectrive WLAN .

Ping-pong effects maybe caused by few APs close to the clients with almost same signal stength, and the Hysteresis value (roaming delta value) in the client wNIC maybe too wide and that's why the device keeps bouncing between APs. That could be a software defect on the client 's firmware, and IT people don't use to upgrade firwares on barcode scanners unless vendor do tell them.

Normally this behaviour should be mitigated after a driver update.

To fix this I changed the DCA interval from 10 minutes to 12 Hours. Now everything works fine.
