Things I've noticed so far from my troubleshooting:
lspci does indeed show the device
dmesg shows:
rtw89_8852ae [...] loaded firmware rtw89/rtw8852a_fw.bin
rtw89_8852ae [...] enabling device (0000 -> 0003)
rtw89_8852ae [...] Firmware version 0.13.36.2 (52acc807), cmd version 0, type 1
rtw89_8852ae [...] Firmware version 0.13.36.2 (52acc807), cmd version 0, type 3
rtw89_8852ae [...] chip rfe_type is 1
rtw89_8852ae [...] rfkill hardware state changed to enable
(and then nothing more.)
iw dev has no output, iwinfo too, ip link only shows lo.
Rebinding the driver (unbind/bind) produces the same dmesg output.
Setting debug_mask=0x1 on module load produces no additional logs.
Which kernel config options are absolutely required for netdev registration on OpenWrt for my hardware? Is there a known issue with RTL8852AE on OpenWrt 6.6 kernels where the driver loads but no interface is created? Should I be using a specific firmware version for 8852AE with kernel 6.6?
Let me know if you need me to rebuild with different configs, any help is appreciated!
Before debugging this any deeper, test a current main snapshot first. rtw89 is a relatively recent driver and the updated kernel (v6.12) and backports versions (v6.14) might make a real difference.
There was indeed a Wiphy phy0!!! I brought it up manually with iw phy phy0 interface add wlan0 type managed. However I do still wonder how come it wasn't registered on it's own
I'm in the process of recompiling openwrt on main with kernel 6.12. but here's the output. I'm running into odd issues with outgoing connections not working, but incoming are.
I used wpa_supplicant to connect to my router to try to get things up and running:
I can't ping 192.168.0.1 (router)
nor 192.168.0.101 (my desktop)
On the other hand though, I can ping my laptop from my desktop, and even access the web interface!
