R8000 Wifi, a lot of devices can't connect to Wifi

Hey
This is my 1st message on the forum and 1st Openwrt install on a Netgear R8000, I've used the oem firmware for few months no problem detected except an boring lags with games, installed Ddwrt for few days everything works well except some Wifi issues, all devices disconnect at the same time (over 20 IoT mcus)
So I moved to Openwrt and noticed almost the same issue with Wifi but this time : Some devices can't connect to my two Wifi networks, radio 1,2,3 am i missing something ?
To sum R8000 wifi is weird with ddwrt and Openwrt

SSH in to the router and run cat /etc/config/wireless.

Redact the passwords in the "option key" sections.

Post the results in preformatted text, by using the icon highlighted in red...

I noticed also a lot of "disassociated" after "associated" like here

Channel 144 is a DFS (radar) channel, and should be avoided.

Use either channels 36 to 48, or 149 to 161.

I noticed you have 'US' on this, and 'FR' on another.

Use the correct country code for all.

Get a WiFi analyzer app to help you find out who is using what channels in your area, your signal strength, and your signal-to-noise ratio (SNR).

I've turned of both Ac radios, I'm focusing on b/g/n radio, right now I can't connect with my phone but the tableat is connected to wifi, some Iot devices also can't connect, it's like there is a maximum number of connected devices to the radio

Reminder: radio0 is still set to channel 149 (DFS channel)

Some clients can't connect using mixed mode.

Try WPA2-PSK with AES instead.

If you have clients that do support mixed mode, set up a separate guest WiFi network for just those devices.
