All,
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 So version 8.2.154.62 will fix all our issues (and is now available for testing) Tonight, I will activate this version for 3100 different access point of which 66x are AP-COS (2802) I hope our wireless network will become stable again after this upgrade....

The only way to get people working again was to associate to a different SSID and then go back. Once we changed our QoS from Platinum or Gold to Silver, the issues seem to have subsided.

Is anyone else experiencing similar issues to this on 2802's? -- Jason Watts Pratt Institute, Academic Computing Senior Network Administrator Sent from my iPhone On Jul 6, 2017, at 7:23 AM, Scharloo, Gertjan <[email protected]> wrote: Hi Bryan, The University of Amsterdam and Amsterdam University of Applied Sciences are currently using 2802i Access Points since December 1, 2016 to gain experience with this new type of Access Point. (Only on the 9th and 10th floors) The access points have been problematic from the start, and still there are complaints from end users that we can’t solve or identify properly. The same users can work without problems on other floors where we have 2702i Access Points stationed in this property. We are currently dealing with client disconnections on the floors/buildings with AP2802i. This disconnection occurs 2-3 hours, sometimes more frequently. Many of our clients are effected. Another issue which is subpart of this issue is: the clients are connected but there is no traffic flow. These clients have laptop from different vendors for example Dell, Apple with different (updated) drivers. -The users stay connected but cannot transmit any data. Two months ago, we have started a new software release 8.2.154.17 and we were hoping to fix our client disconnect issue only with the 2802i AP, but the problem became worse. We have started a Tac CASE (severity 2) Regards Gertjan Scharloo ICT Consultant _____ Universiteit van Amsterdam | Hogeschool van Amsterdam ICT Services Leeuwenburg | kamer A9.44 Weesperzijde 190 | 1097 DZ Amsterdam +31 (0)20 525 4885 Mobiel : +31(0) 61013-5880 www.uva.nl uva.nl/profile/g.scharloo Beschikbaar : Ma | - | Wo | Do | Vr | From: wireless-lan <[email protected]> on behalf of Bryan Ward <[email protected]> Reply-To: wireless-lan <[email protected]> Date: Wednesday, 5 July 2017 at 18:07 To: wireless-lan <[email protected]> Subject: [WIRELESS-LAN] Cisco 3800 Series APs Couldn’t find a recent discussion on the list archives, so I’ll ask my question. For those of you that have Cisco 3800 series APs in production, how have they been working for you recently? We currently purchase 3700 series APs as our standard for new installs and replacement of our 3500 series APs, but are now considering switching to the 3800 series. I heard there were a lot of issues with them at first, but was wondering if they’re still troublesome now that they’ve been out in the wild for some time. Also, does anyone currently have issues using Prime to manage them?
