Immediate disassociation problem on OpenWRT despite sufficient signal?

Hello everyone,

(Please excuse me if I posted this in the wrong topic or if I did not respect some name syntax and others I do not speak English and Google did not want to translate the forum :sweat_smile:)

I am asking for your help to resolve a persistent problem on my OpenWRT installation. When trying to connect to a Wi-Fi network in client mode, the connection seems to be established but ends with an almost instantaneous disassociation. The error messages often indicate "disassociated from XX:XX:XX:XX:XX:XX (Reason: 7=CLASS3_FRAME_FROM_NONASSOC_STA)".

What is surprising is that this problem occurs even when the signal quality seems sufficient, for example with the network "wifi01" where I get a quality of 34 out of 70, which is almost 50%, and signal level -76dBm . Despite this, I cannot maintain the connection. I also pick up other networks with lower quality, such as one at -89 dBm with a quality of 21 out of 70, which indicates that I should have some margin for a stable connection to "wifi01".

I did not try to connect to networks with a weaker signal, focusing on the connection to "wifi01". Do you have any suggestions or similar experiences to stabilize the connection even under these conditions? Thanks in advance for your help.

I'm attaching these photos. Unfortunately these are photos and not screenshots, I couldn't take any at that time :cry:

Thanks

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

Remember to redact passwords, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

Minus 76 is a very marginal signal and -89 is unusable. You want to be in the low to mid 60s or better.

The "quality" number is simply the difference between the dBm and -110. It offers no additional information other than helping people who can't think in terms of negative numbers.
