We've seen issues with large EAP-TLS packets getting fragmented. We also had a specific OS8 release bug affecting AP-515s specifically, but it seems like we're in perpetual bug-chasing mode so I can't recall what version that was. (Probably 8.5 something) (edit: I just saw the 8.5.0.13 in the subject. You may have to move away from that..) On 9/1/21 11:27 AM, Turner, Ryan H wrote: This is a stab in the dark. With the University mostly shutdown since the Spring of 2020 (=not operating in standard mode and most people work from home), we got campus upgraded from 6.X to 8.X code base. We've also installed many 515 series APs. We are getting a large number of complaints in large classrooms that connecting to things like eduroam takes a long time. Looking into the connection, we see many incomplete RADIUS challenges. The general complaints are 'we come into the classroom, and for some folks it can take up to 5 minutes to get connected'. The odd thing is that our RADIUS infrastructure is very large, polished and load shared, and we can see no performance issues with any of the RADIUS servers. We have begun reducing power in the large classrooms to make association issues better, but so far that hasn't changed much. We anticipate opening a ticket with Aruba, soon. We do seem to see the most complaints in the big classrooms. But I do keep going back to the RADIUS Challenges incomplete. I know if no reason for those not to complete unless the connection is broken midway. Has anyone else seen something like this?
