Matt, We are on 8.5.151.0 and we are seeing the same issue dropping/re-associating with the 702W’s but not with the 1815W’s as well. We are also seeing (just started this semester) that devices are associated and connected but unable to pass traffic, this will last anywhere from 30 seconds to 10 minutes (unless they turn off/on the radio again). Seems to primarily impact MacBook’s, they can’t ping or browser to any local or remote hosts during this time.
I’ve had a few cases open with TAC, I suggested the issue being with the 702W’s as well, because we do not see the issue with any of the non-hospitality AP’s in academic spaces or the 1815’s in housing. TAC is saying must be a local RF issue… but I’m not convinced. -Kyle - Kyle Nielsen Senior Network Systems Engineer Information Technology Grand Valley State University 225 Manitou Hall Allendale, MI 49401 office: 616-331-9104 niels...@gvsu.edu<mailto:%7B%20props.email%20%7D> From: The EDUCAUSE Wireless Issues Community Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> On Behalf Of Matthew Craig Sent: Friday, November 20, 2020 12:59 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] 8540 Code version- holiday work Lee, We’re currently running 8.5.135.0, and its been running fine for us for a long time, despite multiple comments on this list of problems with that code. However just within in last couple of months or so we’ve been chasing problems with clients in dorms connecting to 702w (but dorms with 1815w are fine). Clients keep dropping and re-associating; rapid tx errors causing de-associating then coming back in the logs etc... We think something had to have changed on the client side as we’ve had no issues for a long time prior… students bought a bunch of new ax chipsets this semester that don’t like older N radios?, bigsur updates?… haven’t been able to pin it down. Cisco won’t say much more than ditch 702w… but can’t do that on a dime of course. We have been targeting 8.5.151.0 and 8.5.161.0 as an upgrade path to see if it helps. 8.5.161.0 is the recommended TAC release, but I have a somewhat irrational feeling to try 8.5.151.0 first. Your comments about 8.5.151.0 not totally sucking vindicate my feeling! :) - Matt Craig Network Engineer Information and Communication Technologies New Mexico State University On Nov 20, 2020, at 4:30 AM, Lee H Badman <000000db5b77bd95-dmarc-requ...@listserv.educause.edu<mailto:000000db5b77bd95-dmarc-requ...@listserv.educause.edu>> wrote: WARNING: This email originated external to the NMSU email system. Do not click on links or open attachments unless you are sure the content is safe. Knowing that there is no easy answer on questions of Cisco code versions, I’ll throw it out there anyways. We have been on 8.5.151.0 for quite some time now , with mostly good reliability for 3700s and 3800s alike (occasional need to reboot 3700s), We are due to minimally reboot everything, and I’ve been following the various discussions regarding code bugs and specific client issues these past few months. So curious- is there a solid, reliable newer version to consider? We are not in a hurry to get into .11ax yet for a number of reasons. Given the long and problematic history of WLC code, 8.5.151.0 has been as close to “wow, it actually doesn’t totally suck” as we’ve ever been.
