Sporadic wireless client disconnects
Sporadic wireless client disconnects
02-12-2018 02:40 PM
We have been having sporadic client disconnects for months and are looking to see if anyone else with a similar configuration is experiencing similar issues. Aruba TAC is aware of this issue and has escalated it. Outages generally occur for just a few seconds. The client sends a probe request, the AP appears to respond with a deauth a few seconds later, and the client roams either to another AP or another channel on the same AP.
Our Setup
7240 controller running version 6.5.3.3
Each branch location has the following
2x205s - ap mode
1x105 - monitor mode
Bridge mode
802.1X with Radius authentication
WPA2-AES w/Certificates
Mix of versions of iPads and iPad Minis and iPhones
Can replicate the issue on 5th Gen iPads (latest)
OKC enabled
802.11K enabled (Same behavior when disabled)
802.11r enabled (Same behavior when disabled)
Band steering - disabled
A few locations only have a 105 in AP mode and we experience the same behavior there.
The three questions I have for the community...
Is anyone else running a similar setup and not seeing disconnects? Is anyone else running a similar setup and seeing the same disconnects?
Has anyone else found a fix for similar issues that they would like to share?

Thanks for the reply Michael. We actually have client-match disabled currently. That was one of the steps taken in the troubleshooting process with TAC. We modified the radio power to the following a few months back and that hasn't fixed the issue either.

Do you still have a TAC case open? If yes, what is the ticket number?
