Does anybody know if this is only affecting the 2800/3800 series? I have seen some random disconnects coming from 1815w hospitality units.

Upgrading to escalation build 8.5.161.6 helped a lot here. Not sure if that would help your Roku issue, but I haven’t heard of any Roku issues here.

Since then, we have had numerous reports of student devices unable to access the internet in their rooms after connecting to our SSIDs. The #1 reported device type is Roku. Rebooting the access point in an affected area usually allows non-Roku devices to gain internet access for a while. Reading up on Roku inference via Google searches seems to indicate that they have several problematic features such as “Device Connect” and “Interference Mitigation” that cannot always be disabled depending on the type of Roku device and its software version. Our residence halls all have Cisco 3802 access points. We were stuck on 8.3.150.0 until recently but we got rid of the older access points that were holding us back over the summer. We upgraded to 8.5.161.0 around the beginning of last month and there were no reported issues from the few people living the residence halls. This is the only change we have made to the controllers since Spring semester. We opened a case with TAC on Monday about this issue but they have not been very responsive. We had the case requeued yesterday and the new engineer is looking over some logs. I know that devices like Rokus that broadcast their own SSID (hidden or otherwise) have always been a nuisance in the residential WiFi realm but we have never been hit this hard. Is CleanAir bugged in this version? Has anyone else experience this? What did you do to get it resolved?
