We have 3 manufacturing sites, two with IAP-215's, and one with IAP205's. They had all been on 6.4.4.x firmware and had been doing relatively fine (most recently on 6.4.4.8-4.2.4.6).
I upgraded two of the 3 sites a major revision (going to 6.5 - technically 6.5.3.2-6.5.3.2). 6.5.x had been out quite a while so thought it was time to make the jump.
Since then I have heard many complaints from the two upgraded sites about coverages "gaps" that did not exist before. No other settings were changed. Lots of disconnect complaints, and very specific complaining about connections that are slow - and if they move out of that location the wireless becomes more responsive again.
i am not getting similar complaints from the 3rd site that I have NOT upgraded firmware on. I was initially wary of firmware causing an issue, but with the sudden drop in quality, combined with the 3rd site not having issues, the most obvious reason would be firmware.
Has anyone else experienced significant range or disconnect issues after upgrading their instant AP's from 6.4.x to 6.5.x? I checked the ReadMe notes and didn't find anything real helpful. Our clients are running radius and WPA2 authentication, and are generally tablet users (win8 with intel radios) or Symbol 9190 scanners - with 2.4 and 5ghz available.
I am going to try downgrading the firmware soon, but don't want to get stuck on old firmware forever.
Thanks in advance.
