Re: 5.5.24 Controller - disconnected clients showing as connected

5.7.x is unsupported. Upgrade to 5.8.x, the current version of which is 5.8.28. Not saying this is specifically addressed in newer releases, but i haven't experience this in some time.

5.8.28 fixed the issue for me. Easy update.

Re: 5.5.24 Controller - disconnected clients showing as connected

This is still a problem in 5.9.22. The controller is running on an Ubuntu server and there are many wireless clients that show connected to a wired switch port when they are no longer connected. This would seem to be a deal breaker in a corporate invironment where accurate client reporting would be needed. Why is this happening and why hasn't it been fixed yet?

Re: 5.5.24 Controller - disconnected clients showing as connected

We are on 5.8.28 and still have the same issue, the simple anwser is that UBNT doesn't know how to fix this.

 

Look at these crazy numbers.. I monitor throughput on these sites, and we are nowhere near this.

 

AP's with 1274 clients, sure. Man Wink

Re: 5.5.24 Controller - disconnected clients showing as connected

Guys, I have fixed that this way:

 

1) Backup the controller config

2) Install latest debian server (which I needed to upgrade anyways)

3) Install UniFi controller

4) Restore config

 

Dont have this problem anymore, currently on 5.6.30

Re: 5.5.24 Controller - disconnected clients showing as connected

Good Day.

 

We have had the same problems for months now. Currently running on 5.8.28.

We have also had issues with our controller crashing every week due to high CPU usage. Not sure if it is linked to this.

Re: 5.5.24 Controller - disconnected clients showing as connected

It's going to take someone willing to open a support ticket with ubnt and work through this with them. The problem isn't widespread or happen so often that they see it on their own equip. So if anyone has the time, don't try and solve it by backing up and restoring, but instead open a support chat and spend the time working through it.

Re: 5.5.24 Controller - disconnected clients showing as connected

When I look back at what fixed this issue for me, I too did a reinstall (a few months ago) then upgraded to 5.8.28 too in the last few days.  These were seperate incidents, but worth noting.  Something must be gettting corrupt somewhere and the upgrade was needed to fix my over reporting of clients.

 

At my reinstall time, I was having issues with WAPs that simply didn't connect to the controller and showed offline for days.  The support staff were not the most knowlegeable and said that I had to reinstall.  I did so because this particular site only has 9 WAPs and the time was worth more than the frustration.  Bigger sites may need to find the real issue... ;-(

 

I'm using the Raspberry PI controller on this particular site.

Re: 5.5.24 Controller - disconnected clients showing as connected

Re-installing, restoring backups, etc aren't really a fix. Nothing wrong in doing either of those to gain a little sanity. I remember doing this and the problem coming back later. It just hasn't happened to me since the last restore. But the fix will be when this gets patched and is prevented from happening in the first place.

Re: 5.5.24 Controller - disconnected clients showing as connected

This started appearing in our setup with 5.8.28

 

Currently on UCK 0.11.12 (SDN 5.8.30)

 

Only resetting the UCK and restoring from backup fixes this - for a week or two. This affects both guest and user VLANS.

Re: 5.5.24 Controller - disconnected clients showing as connected

Hi, we have been having the same issue for quite a while now. It started several versions ago. Upgraded our controller about 5 or 6 times since the issue started happening and still getting 100's or 1000+ clients showing on a single AP. Did log a ticket with UBNT but no response yet. Controller also been crashing about once a week. Hogging tons of RAM.

Re: 5.5.24 Controller - disconnected clients showing as connected

Yep. Seeing this as well. I'm running 5.9.29 on a CK G1. All network hardware in UniFi. @UBNT-cmb What can I submit that would help with solving this?

Re: 5.5.24 Controller - disconnected clients showing as connected

[ Edited ]

Running controller 5.6.39 (still have some old APs in place).  Same issue.  DHCP has a lease time of 4 hours for guests.  Obviously there would be IP conflicts if these clients were connected, as the controller seems to think.

 

Rebuild the controller is not an valid option.  I just build this one about 6 weeks ago.

Re: 5.5.24 Controller - disconnected clients showing as connected

Hi

 

I have the same issue, connected client list is growing....

Workarround is rebooting the cloud key, but it makes the guest network unaccessable at that moment.

Have you tried pruning the database?

Re: 5.5.24 Controller - disconnected clients showing as connected

I did compact the data, now it's OK again, but can't this be done automaticly?

The problem will reoccur.
