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?

Good morning, @Sam Pirok I hope you’re doing well this Friday. How are things looking?

Of note, these graphs change drastically depending on which “Time Range” is selected. I’m seeing this across all of my models and firmware versions.

I’ve not been able to correlate issue with these dips, but we are having many reports of disconnects across multiple sites, models, firmware all with the symptom of - Connected “no internet” - Most of which started toward the beginning of Jan.

I’ve been delaying working with support until I had more info on my end as I wanted to ensure we weren’t having some other internal issue. Also it’s extremely difficult to catch such an intermittent issue in the act.

Looking just now I’ve confirmed this type of graph behavior (I pulled up all my stragglers that aren’t on latest FW to give a broader picture)

AP550 - 8.0.1.0, 10.0.8.1, 10.0.9.2

AP250 - 10.0.9.2

AP230 - 6.5.11.0, 10.0.8.1, 10.0.9.2

AP330 - 6.5.12.0

AP121 - 6.5.12.0

Thanks very much for the extra details guys! I hear the engineering team has found some “interesting things”, still waiting on details on that but progress is being made!

@Sam Pirok This is from AP NCPS-AP650-RM305, one of the tech data AP’s that I sent. They were being disconnected and having performance issues during the times of the dips.

@Sam Pirok 

I only rolled back one device so far: GW-MDF-2

This was at about 10am CST yesterday, 1/27.
