I'm seeing this on my EAP620's now. I'm trying to connect Chromecast and nest devices and everytime I add one (in google home), two I had already added appear again! I'm seeing the same association errors.

We started getting association errors for the main clients cell phone on her EAP660 after the last visit to the site. Getting about 6-10 a day just for her cell. The site has 1 comcast connection and it is being split to the 4 networks.  

On the last visit we added a switch and did fiber runs to the other 3 clients. To replace old Cat5e connections. Then I did a firmware update on the OC200. Did not touch the main clients EAP or network settings. The client has not complained. But it is showing in the events log when.

Still getting this issue after 2 years having edited the beacon interval and reset site config and reset access points.
Asking TP link for assistance, but we'll see how that goes. There's quite a few threads regarding this issue and im surprised its still a thing. I was thinking it was mainly due to slow devices as most of the issues plague my rasberry PIs, but one or two errors come from my windows surface and that is not sluggish at all!

My only fix is to replace the wifi devices, which is OK with wifi dongles, but if it happens to one of the iphones, i think it will be omada that has to go in the bin!!

Omada 4.4.5 on docker, 2x EAP3225 v3 fw5.05, 1 eap outdoor, 1 x EAP110

If someone answered how to get rid of them - I missed it .

While settings things up and learning how to work the system - I am getting tons of these .  I would like to clear them and see how many are happening over a certain time period .

EDIT

edit

I am just trying to figure out how to clear the failures on the controller dashboard

Look here for details of how to reset the counter, look here;  Resetting the OC200 SDN Dashboard Association Failures Widget - Business Community (tp-link.com)

To fix it, god only knows

Not sure if its was from the mutilple controller reboots I did yesterday
