I don't know Lee, within our consortium of 5 undergrad and 2 grad universities, all running AireOS-based WLCs, the reliability has been exceptional. My last show-stopper (WLC crash) was way back in 5.x days. Sure, there have been AP radio code challenges, but most of those were wayward client devices that had to have their behavior dealt with at the AP radio code level.
This is purely my experience, but when I ran into those AP<->client radio issues with my first customer ship 3800's, the Cisco wireless BU worked directly with us on resolution, with rapid radio code updates to work around the client challenges. I couldn't ask for a better relationship with a vendor. It surprises me that any vendor's WiFi in EDU's work reliably given the myriad of client devices, OS versions, and chipsets we deal with. It was certainly the case when my consortium had Aruba too, that the grass wasn't greener... they had their gopher problems, and Cisco had prairie dogs. I do think the future is in SaaS/IaaS, where the vendor has much better visibility on its installed base, and can capture assurance data to help with rapid code improvement. The reality is, must customers aren't sophisticated enough, or have the teams in-place, to diagnose WiFi issues, but a vendor with insight into their installed-base deployment would.

I'd go so far as to say that I have never seen or heard of a buggier product set than the AireOS WLCs. I can't imagine Airespace would have survived over time had Cisco not bought them to get into the thin AP paradigm given the chronic code issues.

Typically I've monitored the release cycle on patches to determine how "bad" things were. In the olden days, Cisco would release a patch when a fixed number of serious issues were resolved. You could then track how many serious bugs were being fixed by the interval between patches. Quicker patches means more issues with a higher severity. If the intervals between patches went down, things were starting to stabilize. So if you saw a patch two months in a row, it might be a "let's wait for the next one." Not sure that will hold true, now that Cisco is saying that "all" releases will be stable-train moving forward for ISE. I see it's been a while from 2.7 to 2.7p1. That could be a good sign. Typically I would wait 2 months before upgrading to make sure there weren't repeated patches. You see this even with some long-lived trains that have patches 8,9,10,11 all very close together.

Cisco released very few new features and instead focused a lot of bug fixes in 2.6 and 2.7. ********** Replies to EDUCAUSE Community Group emails are sent to the entire community list.
