No WiFi on latest image

VaRusLAN · May 29

I installed latest Armbian_24.5.1_Orangepi5-plus_bookworm_vendor_6.1.43_minimal.img and I can't get wifi to work. The adapter is RTL8852BE. I installed armbian-firmware-full and the adapter is shown in lspci, but there is no wireless interface. armbian-config does not list wifi as an option. armbianmonitor -u

Ok, so I saw that wifi works on latest kernel and I decided to give it a try. And now it works!

I just had to delete vendor packages and install their edge counterparts

armbian-bsp-cli-orangepi5-plus-vendor  -> armbian-bsp-cli-orangepi5-plus-edge
linux-dtb-vendor-rk35xx                -> linux-dtb-edge-rockchip-rk3588
linux-image-vendor-rk35xx              -> linux-image-edge-rockchip-rk3588
linux-u-boot-orangepi5-plus-vendor     -> linux-u-boot-orangepi5-plus-edge

Switching to 6.8 kernel was not the solution. On 6.8 kernel there is a problem with the video and the idle cpu temperature is much higher than on the vendor kernel (44 °C vs 52 °C), so I had to switch back.

I checked kernel binaries on 6.1 and 6.8, and there is no rtw_8852be.ko on 6.1 vendor kernel. 6.1 kernel config does not even mention it. I went to the official linux-orangepi repository, cloned it and found out that there is a support for RTL8852BE, it just needs to be enabled.

I couldn't find how armbian repositories are being populated. Which git repository is being used to build vendor kernel? What revision? If someone could help me find it, I'll add the patch myself.

apt.armbian.com is published at point releases, from this branch https://github.com/armbian/build/tree/v24.05 If you check it out, you will get identical what is on stable repository. If you want to go manual way, here https://github.com/armbian/build/blob/v24.05/config/sources/git_sources.json are information about sources.

beta.armbian.com is published every x hours from trunk https://github.com/armbian/build

If you want to see how this is done, peek into this code.

Kernel 6.8 and 6.1 are very very different. Don't expect 6.8 to work better or that all functions will work. Some are not even developed - it is being developed from scratch for around two years now. Code is changing fast, so there is not possible to provide any support. Its too expensive and useless. If you want dig in, but expect troubles and very little response as not many people deal with. 6.1 is different. All 3588 share same problems ... more or less and there is a lot of support in forums.
