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?

Unfortunately, the rollback to 10.09rb didn’t correct the lag and random disconnections. After I rolled out 10.2r4 on 1/10/2021, things were quiet overall until maybe the 15th. Then more issues crept up with random disconnects last week. This week it’s worse and reintroducing 10.0r9b just added an extra layer of divine icing on top. I’m just trying to provide a timeline based on incidents and teacher feedback.

It’s so bad we’re having to hardwire teachers laptops

@kevin.piazza Thank you for getting that data together for us! I took a look at the client monitor, but it’s all normal connection messages and some generic disconnection messages. I’m going through the tech data now, also talking to the tech on your case who is reviewing the same data too, so far we haven’t found anything helpful but we are still looking there. 

@javabomberman, I heard from the engineering team looking in to this for us and they’d like to compare data from before you rolled back the firmware, do you remember approximately what time you rolled the firmware back to 10.0r9 on your APs?

@Sam Pirok Thank you very much for your assistance. I’ve uploaded two AP’s worth of auth diags tech data, along with a GUI diag for one of devices. I hope we can have a better idea of what’s going on ASAP. ? to you Sam!

Thanks Kevin, sorry to hear it’s been a rough morning  It would be good to attach all that to your case so our engineers can all see it, but please also let me know when that’s available and I’ll take a look too to see if anything jumps out at me. Good luck, and please let me know if I can help with anything. I’m pretty open today if you need help and want to jump on a call.

@Sam Pirok I’m trying to get auth debugs from two AP’s for you, along with some client monitoring info. It hasn’t been a pretty morning with WiFi ?
