Connectivity problems after update to 6.4r1

I don't know if this is a coincidence but after updating AP230's to 6.4r1 yesterday a lot of clients are having connectivity problems.  In the event log I see a lot of deauthentication events but don't know the significance of that.  On some older Dell laptops (Latitude D630) they indicate that they are connected but with no internet access.  iPad Air has the connection indicator spinning endlessly.  I had made some changes to radio rate settings for one SSID but have since changed them back wondering if they had caused problems.

If anyone has suggestions I'd be grateful to hear from you - I've got a lot of people suddenly unable to connect and have had to bring an older Sophos (Astaro) AP back online to limp along.

Thanks,

Steve

Did you attempt to revert back to a previous code version to see if the problems went away?

I haven't tried that - I guess I will if I can't get to the bottom of it quickly.  Thanks.

Pick a client and run Client Monitor.

Best,

Here's a potential breakthrough - everyone with problems seems to have been connecting to one of two AP121's that were still running 6.4r1.  I took those offline and all my test devices are working now.

I see where to roll back the Ap121's.  I'll give that a try and see what happens.

Thanks,

Steve

Steve, i have also experienced that the issues went away with a rollback to v6.2r1.

Please confirm if that fixes your issues as well. Im currently rolling back the last school we have. The full "test" is tomorrow when 4000+ students comes back to the school.

I suggest then that you open a support case so that somebody with remote access to the APs and your HiveManager can identify what's going on. There is only so much you can do best-guessing through a forum.

Yes, the output from Client Monitor for an affected client would be helpful if you have it.

FWIW, I updated an educational site to 6.4r1, ~200 APs (mix of AP330s and AP230s), a few weeks ago and there haven't been any reported issues.

Thanks.  It certainly seems to involve the OS version but just how it's interacting with other parts of the network is a question.  The gateway is on the Sophos UTM425 - maybe there's some idiosyncrasy there that's causing the issue.  I'm going to want to be able to keep the OS up to date, so I will contact support.  I doubt Sophos would offer much help for non-Sophos gear. I wonder if Aerohive will be able to help me figure out where the problem resides (especially if there's no bug in the software).  I'll come back with an update if /when I have one.  I appreciate your help.

Once I realized I had two AP121's still on 6.4r1 and rolled them back I'm back to normal operation.  The update is clearly working fine for a lot of people, so I'll contact support to see if they can help me figure out what's going wrong in my environment.

We don't use AP121, but use the AP230's.....in case it applies, there seems to be what I call a silent release of 6.4r1a.... (It just showed up replacing the original version in my list)

We had a LOT of strange issues happening here after move to 6.4r1...  

AP's dropping off and in most cases we literally had to pull the network feed to them.  You couldn't  reboot them to get them back online, nor would resetting PSE at the port level OR the switch level worked.  In fact, resetting POE to them didn't work unless we moved to another physical port!
This was worked on with support.... all the way to level 3.... SR2124 & SR2148 switches lost POE in all but 1 port!
The affected SR2124/48 switches had to be replaced as even Level 3 couldn't make them work after upgrades.

All the other "anomalies" seem to have resolved with the updating to 6.4r1a....   There was one issue noted with THAT release -- some of my switches gave warning that they couldn't reserve the  VLAN 3967.    

Unclear at this point with regard to the VLAN warning, but I've seen no impact and no further errors across the board since *6.4r1a* was inserted.

One other consideration --- We use Hive Online, not the appliance method.  @Nick notes that they did the same update with no issues at all, and we have about the same overall size with 146 AP230's and a mix of SR2024/SR2124/SR2148 switches.

Thanks for all of the information.  We also use HMOL rather than the appliance.  It would be good to know what there is in common among the networks that have had problems with 6.4v1.  We're a pretty small operation with only 10 AP's.  Our switches are not the newest - two Cisco SG300 and two Procurve 2810.  The router is a Sophos UTM425.

Perhaps I should try 6.4v1a and see how it goes.  I look forward to further updates and I'll post back here if I learn anything - I did open a ticket yesterday.

I thought things were all right but I think I've been having too many devices connecting at 2.4 GHz that should be able to use 5 GHz, so I'm about to check the configuration.

We have about 120 AP 230 running on SR2024 swithes with version 6.2r1a and are we are having connectivity issues on 5 Ghz. When we reboot a AP that do not accept client on 5 Ghz all works fine for a while.

I've also can confirm that the 5 ghz band is causing issues when AC is selected on its profile it's radio profile.

Thanks for the information - I think we might be experiencing something similar.  I'll check the configuration.

Thought I might be alone.. but this is interesting... We are having massive roaming issues with our chromebooks and iPads. If you run the client it shows it trying to connect but then it says de-authenticating due to driver. The laptops we have don't see to have this issue when roaming.

It's causing a major headache

Have you tried enabling the Voice-Enterprise features on a dedicated SSID for 802.11k?
