Seeing that these printer are very important for the production flow, we had to perform a downgrade to the previous release and luckily the roll back solved the issue.Īnyway for more then one reason we ought to perform this upgrade, so we prepared a lab to better understand what happened and find a solution. ![]() After we upgraded WLC from rel 8.2 to 8.5 we had a bunch of WiFi printers not able to associate anymore to our Cisco APs.
