We only have a handful of 3702i APs deployed but do not recall anything specific to that model. We moved from 8.0 to 8.2 for similar reasons though. I doubt this is related with the random disassociations but we took Lee Badman’s suggestion to turn down the client exclusion timer from 60 seconds to 5 seconds on our dot1x SSIDs. It seems to have helped incorrectly configured and/or poorly behaving clients a lot yet still provides some level of security.
I would guess everyone else knows this but running 8.0, 8.2, and/or 8.3 across the same RF grouping may give you unpredictable results. Specifically 2800/3800 APs that I tried to let do auto channel width in a small area….. for that area it worked fine until an 8.0 WLC was the RF leader. At that point all of the APs on the newer controller code that supported auto channel width went to 80MHz channels. It was a quick fix but it made me think someone was messing with me for a while…… *Mike Atkins * Network Engineer Office of Information Technology University of Notre Dame *From:* The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] *On Behalf Of *Eric Glinsky *Sent:* Friday, March 10, 2017 2:56 PM *To:* WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU *Subject:* Re: [WIRELESS-LAN] Cisco WLC code recommendations If I may add to the question, does 8.2.141.0 solve the roaming issues with Apple devices and the association issues with 3700s seen in 8.0? We’re on 8.0.121.0 and we’re experiencing delayed association/roaming, particularly on Apple devices. 8.0.140.0 improved roaming but caused devices to randomly disassociate for a minute or two at a time even during use when stationary, so we downgraded.

The update helped with some 2802 issues we had with the radios getting stuck or the APs crashing. I think it also had some improvements with the auto channel width but we had already abandoned that dream by then. *Mike Atkins * Network Engineer Office of Information Technology University of Notre Dame *From:* The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] *On Behalf Of *Entwistle, Bruce *Sent:* Friday, March 10, 2017 1:53 PM *To:* WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU *Subject:* [WIRELESS-LAN] Cisco WLC code recommendations We are currently running version 8.0.133.0 on our Cisco 5508 controllers, as our current access points are primarily 3500s and 3600s. However we have recently purchased a batch of 2802i access points whose minimum supported version is 8.2.110.0. I was looking to the group for their recommendations on a stable version of code which will support our new 2802i access points.
