We have started a new TAC-case : SR 682611042 : Disconnecting clients associated to 2802i AP's (But i think my problem is related to software version 8.2.154.17)
07-12-2017 01:48 AM
We found our client - 2802i AP problem. They are all related to a memory leak in the 2802 AP : (This problem has taken us crazy for 6 months!)
CSCve55196 COS AP not forwarding DHCP OFFER/ACK on its radio downstream
CSCvd64819 AP-COS drops downstream DHCP; kills wpcpd (reason: OOM); kernel panic
(they will be deduplicated)
CSCvd23175 2800/3800 WCPD memory leak observed
And our flash issue is fixed in :
CSCuz47559 error saving config file happens on multiple 2702

Do you know if 8.2.154.62 is available through the same registration process as for the original version of this post? Or did you have to ask the TAC for it?
07-13-2017 02:31 PM
Same registration process and you can download this version from: https://upload.cisco.com/cgi-bin/swc/fileexg/main.cgi?CONTYPES=wng-escalation
07-14-2017 10:20 AM
UPDATE : Our client problem is still in version 8.2.154.62 and hard to reproduce(!)
07-14-2017 10:26 PM
What problem is that? I'm also running this code now..
On a 5508 controller, I've found a very easily reproducible controller crash bug. Just go to the Network Dashboard > Select an AP from the top 10 list (that cas clients attached) > go to the clients list tab in that view > Select a client in order to load the details about it. And BOOM, the controller crashes.
Can anyone else see if they are having the same issue and contact wnbu escalation with additional info, such as controller crash logs etc?
07-16-2017 07:44 PM
Yep, we're seeing the same, CSCvb32922 is the bug we've been provided, fixed in next build.

New build out now, where this is said to be fixed. Version 8.2.154.67 .
09-01-2017 01:06 PM
After three months of throubleshooting and collecting wireshark (RF/LAN)captures. Cisco found this bug in 8.2MR6: 2800/3800 AP not passing traffic, Symptom: Wireless Client when auto-connects to SSID unable to reach gateway #CSCve57121 We are waiting for a fix (This bug is the root cause of disconnecting clients in our environment)
09-09-2017 01:59 AM - edited 09-09-2017 02:04 AM
8.2.163.3 (8.2 MR7 Interim Release) is available) and fixed : CSCve57121(!), CSCvf28800, CSCvf60803, CSCvf02705, CSCvf23975 and CSCvd16380 (DFS False triggers!)
06-27-2017 05:39 AM
Our partner(Axians) needs more logs to open a new Tac-case(again). There is no TAC_CASE on this moment for our client problem. The disconnect client problem is very hard to identify. It's completely random...
06-23-2017 01:32 AM
Is there any update or any progress for 8.2MR6 ?
06-27-2017 05:22 AM
We are running version 8.2.154.17 now for two months and we have serious problems with a few clients(disconnects without logs on controller and ap) on 2802i and we can't solve the issue! . What's going on?!
Why is there no update?!
Should we switch to 8.3MR2 because of these bugs CSCvc06325, CSCva37010.
HELLUP !
06-28-2017 03:35 PM
Should we switch to 8.3MR2 because of these bugs CSCvc06325, CSCva37010.
Do you have wireless voice application in your wireless network?
Was the issue evident in 8.2.141.0?
07-04-2017 02:37 AM
We are using Wi-Fi calling in our network and students are also using this new (ISP) feature.
In 8.2MR4 we have similar client issues with 2802i
At the moment, we are 'familiar' with the following 2802i AP issues and they are not solved in 8.2.154.17(!):
CSCuz47559 : "error saving config file happens on multiple 2702"
CSCvd66657 : AP "3802: SensorD stuck in offchannel causing radio stops working"
CSCvd99909 : AP "3800 - 5G Radio crashes - when SI enabled"
CSCva37010 : invalid staid XXX received
CSCva37010 : "3800 5GHz stops accepting client, auth response not sent."
CSCvd90117 : "AP3800 - Radio crashing frequently due to beacon stuck"
CSCvd91894 : "3800/2800 kernel panic crash PC is at mv_dev_kfree_skb+0xc/0xa4 [ap8x]"
CSCvd16380 : "3800 detecting DFS False triggers"
CSCve26948 : "AP2800/3800 Capwapd Blocked during Ap boot causing watchdog reset(wcpd)"
CSCvb67378 : "Too many channel changes occur on dual radio IF working as 5 GHz"
CSCve13183 :"Cisco 2800, 3800, 1800 APs WCPD reloads unexpectedly due to double-free in RRM Off-channel element"
Where is the update for the 8.2(preMR6) train?!
