Espeasy: Disconnected! Reason: '(8) Assoc leave' Connected for 12 s

[s0170071]

What is this Assoc leave? This goes on forever on one of my recently updated units.
I am still in the process of finding out how far back this goes...

8
Disassociated because sending STA is leaving (or has left) BSS
Operating System moved the client to another access point using non-aggressive load balancing.

[s0170071]

hm.. error is gone after I factory reset and re-configured the unit. It could be a bug but I see little chance of reproducing it.

[burkulesomesh43]

@Grovkillen Can you please explain in detail non aggrasive load balancing?
I am also facing same issue related to wifi. getting disconnect reason ASSOC_LEAVE(8).

[Grovkillen]

To my knowledge the non-aggressive load balancing is that it the AP is busy and the client is trying another AP. But I'm no expert.

[TD-er]

Aggressive Load Balancing and non-aggressive load balancing are indications the selected AP is responding with a "busy" reply when you try to connect a client.
The difference is that with the non-aggressive variant the client will finally get a successful connection after some number of retries.

So, is your AP busy?
Is it still a problem after rebooting the AP?
It is quite common for a client to get disconnected from the AP. It may become an issue when it is hardly possible to reconnect.

My ESP8266 D1 Mini drove me crazy by disconnecting from my home wifi about every minute with message: Disconnected! Reason: '(8) Assoc leave'
No ESPEasy configuration changes made any difference. After few days I finally found the problem - in my case it was DHCP server client lease time on my Linksys router, which was configured to 1 minute! Changed it to 0 (which means one day) and disconnects stopped :)

[TD-er]

That's also good to know.
I am looking into the (other) WiFi issues right now, so I will try to keep in mind to add a warning if the DHCP TTL time is too low to be practical.
