We’ve been running 7.6.120.0 with very few problems for quite some time. It’s been one of the more stable versions I’ve run into.

I had to upgrade to intermediate version 7.4.121 to enable predownloading to work.

Crashing due to web auth, resolved in 7.6.122.6 (aka MR3). 2. Any newly provisioned AP would have its radios immediately disabled, the only apparent workaround was to manually shut/no shut the radio interfaces on the AP itself. 3. A certain mix of non-cisco PoE & cable length caused APs to only request 5W of power and leave their radios disabled, taking out large sections of wireless coverage. To top it all, when I reverted to 7.4.121 after 36 hours of the above, the entire campus radios were disabled in a similar way to fault 2. above, eventually resolved this though. We'll be waiting for 8.0 now to support our [23]700s, and even then only after it's been released for a few months. Getting a bit fed up of beta testing Ciscos WLC code on our production network.

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<tel:%2B61%208%208313%204800> e-mail: [email protected]<mailto:[email protected]<mailto:[email protected]%3cmailto:[email protected]>> From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]<mailto:[email protected]>] On Behalf Of Kitri Waterman Sent: Friday, 1 August 2014 2:17 AM To: [email protected]<mailto:[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?
