As a few others have mentioned, if you are running webauth get a recommended MR from TAC otherwise you’ll get crashes
This seems a somewhat reasonable page as well. https://supportforums.cisco.com/document/7721/wireless-lan-alerts We had 3 AP’s fail upon pre-download of the image(came from 7.5), so yes they died during pre-download not during the actual upgrade. 1 came back but 2 now need replacement. Seems the same as what Kitri mentioned but our attempts to recover didn’t work so well. We followed a different process though. Had to reboot our 3602i AP’s with 11ac modules a second time after upgrade from 120.0 to the MR 122.6 release as 11ac clients couldn’t get DHCP. So if you ignore controller crashes, AP failures and extra AP reboots … it’s been smooth…….. There’s also a field upgrade image to go with the 7.6 code Yes we’ll follow the amen to a good stable code. They promise a lot for code 8 but I won’t hold my breathe yet. -- Jason Cook The University of Adelaide, AUSTRALIA 5005 Ph : +61 8 8313 4800 e-mail: [email protected]<mailto:[email protected]<mailto:[email protected]%3cmailto:[email protected]>> From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Kitri Waterman Sent: Friday, 1 August 2014 2:17 AM To: [email protected] Subject: Re: [WIRELESS-LAN] Cisco Controller Code We've run into an issue with some older APs (3500 and below) where they've gotten stuck trying to predownload a new image. The solution was deleting the recovery image from the AP and then initiating the predownload again. And another amen to the frustration with finding good stable code!

We have a lot of 2600, 3500 series AP's and some legacy 1142 and 1131's. We are thinking about moving to 7.6.120.0. Has anyone had experience with this version ? Any issues? recommendations?
