```
Can somebody confirm this bug on 25.10.0, too ?

BPI-R4 snapshot here (2025-04-04)
It did not happen with the version of a couple of months ago (but I did have other ssh stability problems), now I can't reboot without this happening.
fortunately 5ghz is stable enough that I can just login, change really anything in the unusable 2.4g, apply and it works again.
I tried wpad-mbedtls, wpad-openssl, hostapd-openssl hoping it would change anything, someone suggested introducing delays at boot, like:
wifi down radio0
wifi down radio1
wifi down radio2
sleep 5
wifi up radio1
sleep 90
wifi up radio2
sleep 30
wifi up radio0
but it does not help.
I have a rough feeling it's due to having multiple SSID on 2.4ghz since 5g and 6ghz seem to work fine and I only have one ssid there.
The workaround is probably to limit yourself to 1 ap per radio.
