Had seen this once, so asumed it may have been a client issue so left the PC guys looking at it, however, Ive now seen this on 2 other occasions.
The SSID is broadcast out of all groups across site, the client seems to connect fine apart from in one area. The AP is in the same group as others that the client will connect to fine. So if the device goes to an adjacent area, it will connect, return it to the problematic area, it wont connect. My laptop connects to the AP and SSID fine, but this other device wont.
The only thing that I can think of that may be a link or just conincidence, is that these APs were converted 315 IAPs. The recent batch of 315's we have received have all been instants, unlitke the previuos 100+ we had. But having said that, the AP is in a main group with other APs that doent seem to have issues.
So far this problem is apparant in two seperate areas on site across APs in two different groups. But seems very localised to certain APs.
We have 7220 controllers, running 6.5.3.3 code.
Does anything obvious spring to mind, before I start looking at AP/Cleint debug logs? Any commands in particular I should be looking at, as not overly familiar with debugging.
Thanks
