10.2r4 firmware causing AP650's to lose connectivity?

[KevinP1]

Okay, I don’t know what’s happening here but this isn’t looking pretty. All of our AP650’s are losing connectivity multiple times throughout the day. 

Look at this! Some AP’s will only do this once or twice and others are doing it often, like this ? There’s nothing indicating any type of error or issue. We didn’t have this problem on firmware 10.09rb.

I have a case open with GTAC, but are we the only ones seeing this issue?

Thank you for the screen shots @a.huerzeler ! Yes we are able to reproduce this, they were originally thinking it was an issue with 10.2r4 but I’ve shared all of the findings you all have shared with me, and they are looking elsewhere.

Unfortunately I don’t have any details beyond that yet. I imagine a bug report is in our future, if you haven’t filed a case already I’d encourage you to do so. I’ll keep updating you here as I learn more, but once we do have a bug open, it’s good to have several cases attached to the bug so we can keep momentum up on the resolution.

@kevin.piazza I don’t know if am just not able to or if its not possible but cant go back in time in the 1, 2, 4, 8 hour views but the recent ones look ok. I have had one hick up which shows as roaming event but doesnt show in the graphs (was around 20:04) which is weird because its a single AP and the Apple TV which is my test client is in plain sight of the AP and has excellent connection stats. But compared to 10.2r4 where the connection was dropping ~45 minutes it looks better but……..
 

@Sam Pirok Are you guys able to reproduce the problems in your labs? Did you get any news from the engineers?

[KevinP1]

@a.huerzeler I see in that graph that you have it on 24 hours. What does it look like with 1, 2, or 4-hour intervals?

@a.huerzeler , that is interesting, thank you for letting me know! Would you be able to send me your VIQ name? You can find that in Global Settings> VIQ Management. If you’d rather send that directly to me please feel free to email me at community@extremenetworks.com.

@Sam Pirok On my test AP (AP410C)  it looks really good since the downgrade to 10.2r3 last night
