It is brcmfmac, means at least one function can work....

Sysupgrade wiping config https://firmware-selector.openwrt.org/?version=25.12.0&target=bcm53xx%2Fgeneric&id=asus_rt-ac5300 (DO NOT CUSTOMIZE PACKAGES AND SCRIPTS)

At least there is wifi driver included and it is supposed to work.


Not sure whatis the point of pictures...

no it doesnt work

How do you know? do you see any errors running iw phy ?

Kernel boot log / dmesg could tell why brcmfmac didn’t kick in

Sorry - i said "please do A" - you just "yeah, ill do B"


it show only error -2 ,thnx for your support

Please use the "Preformatted text </>" button for logs, scripts, configs and general console output (red circle; this works best in the 'Markdown' composer view in the blue oval):

Weird. Interesting. It seems RT-AC5300 was expected to come with BCM4366C0 chip but your unit appears to have BCM4366B1.

You need to install brcmfmac-firmware-4366b1-pcie package manually (and reboot).
