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?

@w1f1n00b sorry for late, Yes, I mean 10.0r10a, the last comment has a typo. I saw the kb you aforemention, but the defective version is 10.0r10, and have been fixed by 10.0r10a.

by the way, what does ah_dcd do? why the client drop connection when it crash.

Several months back I finally upgraded my APs from 10.0r8a (seems to be a good stable release) to 10.0r10b and haven’t had any noticeable issues. I’ve currently updated around 600 APs to 10.3r3 but won’t have much feedback/comparison until the school year gets in full swing over the next several weeks. Assuming all goes well I’ll be bringing everything up to 10.3r3 by early Sep. Keeping a close eye on forum and docs in the mean time.

you said “10.10ra” I’m assuming you mean 10.0r10a? Just want to be sure and steer clear of 10.0r10, as that release had some pretty big issues, and was not recommended for use last I checked (https://extremeportal.force.com/ExtrArticleDetail?an=000060590&q=%2210.0r10a%22). It would be nice if there was some type of master list of firmware versions, and which ones have which issues, so people aren’t repeatedly shooting themselves in the foot looking for stable versions.

Hi guys, beside ap650 with 10.3, I am encountering a random connection drop situation or associated but not traffic pass through. My device are ap230s with 10.3r3, and I have tried 10.10ra and 6.5r11, 6.5r11 was the most stable firmware.

But isn’t  the newer the better?

@w1f1n00b Well look at that, there’s an actual Article now. Thank you for bringing that to our attention. The engineer I worked with couldn’t figure out why the memory dips were being displayed on XIQ. However, we came to the conclusion that it needed further looking into. We didn’t believe there were any synchronous memory drops occurring on the AP’s themselves, but all of us have had this issue within XIQ for a long time now.
