We have 5 Cisco Aironet 1100 wireless access points and we are having huge problems in the last few days with them disconnecting some mobile barcode scanners that we have.
We have two Aironet's in the top of the factory which work fine and 3 down the bottom which keep kicking the barcode scanners off. If we use the barcode scanners at the top of the factory they work fine, as soon as we come down to the other 3 WAPs it they keep connecting and disconnecting.
We get the following error in the Event log on the access points...
Disassociated because sending station is leaving (or has left) BSS
On the barcode scanners we get this message...
Associating - mdc-ap does no
We've tried changing the channels on all 3 wireless access points but the problem still exists.
Has anyone else experienced anything like this or have a potential solution? The WAPs are running software version 12.3(8)JEC
Here's an example of an event log on the WAPs...
