Wireless Access

Helle everyone, 

     We have a very strange issue since we migrated from AOS8 to AOS10 this summer: all our students laptop that use computer certificate authentification (EAP-TLS) are experiencing now constant disconnect/reconnect to our 802.1x SSID.  What happens during the disconnect/reconnect phase is that the computer enters a "roaming storm" and roams to all AP that it sees, even the ones with a very weak signal. During this "roaming storm" the computer loses connection to the network from anyware of 3 to 15 seconds.

     What is very strange is that the same computer, in the same location, is very stable on the network (stays connected to the same AP, no lost connections) if it connects to the same SSID but with a username/password instead of a computer certificate.  Everything was super stable with AOS8.

      We opened a case with the TAC but they are still investigating the issue.

      I was curious to see if anyone else experienced or is experiencing this same issue.

Thank you,

Antonio

what firmware are you running?

Tried AOS 10.4.1.5, 10.7.0.0 and 10.7.0.1 and problem is present on all 3 firmwares.

TAC confirmed to me today that they are opening an engineering ticket.
