I have just installed 2 4402 WLAN controllers.
I have 4 different types of devices to test to confirm connectivity:
laptops - successful
LXE RDT's - successful
LXE MX6 scan-gun - successful
Zebra label printers - UNsuccessful
There are multiple vlans in the controllers, and the Zebra printer is, oddly enough, on the SAME vlan as the RDT, which connects fine.
When I look at the client association page in the GUI, the RDT shows YES in the AUTH column, and the Zebra printer shows NO. Also, the laptop and the scan-gun also showed YES in the AUTH column, and they connected just fine.
Any thoughts as to if this might be the problem, or if not, where I should look?
