I am having problems with LEAP authentication, was working fine and without any reason, AP does not send correct packets to Cisco Secure ACS, configuration was not changed, simply stopped working, now when trying to associate clients, logs in AP show this message: Station 000476a6277c Failed Authentication, status "Unsupported Authentication Algorithm".
But was running before!!!
Placed a sniffer and don´t see traffic between AP and Cisco secure while authentication process, but Cisco Secure sees AP via a ping.
I am running version 11.42T in my AP and want to know what version is recommended to upgrade it. If you have any suggestion, and if there´s not inconvenience from you, want to know if you also have the link where upgrade procedure is explained.
