Problems with LAN Adapter Geekom Mini PC Air12 Lite

Installation
1

I have a Geekom MiniPC Air12 Lite and would like to install Homeassistant. The instructions I used are from Matthias Kleine. With an Ubuntu Live system I can’t access the LAN interface, only the WiFi, but when Homeassistant was flashed, I can’t configure the WiFi interface, LAN doesn’t work either. Flashing the SSD on another computer doesn’t give any better results. eth0 and wlan work only with win11 without any problems.
Does anyone know a solution

The WiFi interface can be configured but the Ethernet interface is not a mainline supported device. See: Ethernet adapter Motorcomm YT6801 Gigabit Ethernet Adapter support in HAOS · Issue #3387 · home-assistant/operating-system · GitHub

I am returning mine as I don’t want a device that is not supported.

I should have bought the GMKtec G3 as it’s already been tested. See https://youtu.be/nKG14jXVydI?si=-xm45IizRE-lBTqk

And it’s cheaper https://www.gmktec.com/products/nucbox-g3-most-cost-effective-mini-pc-with-intel-n100-processor

The solution to the missing device driver is to compile the ethernet device driver from here 20210819_LINUX_BT_DRIVER_RTL8852B_COEX_v0606

I am choosing to return my device as I don’t want the worry of HAOS failing every time there is a kernel update. A return fee of 5% is charged. Which is probably less than the delivery cost, so it’s not too bad. I have now learnt to better check compatibility (and not believe supplier blog posts).

In summary, if you purchase a Geekom NUC to run Linux or Home Assistant OS (HAOS), you may end up having to compile device drivers to get it to work.

Just use a USB → Ethernet dongle (choose the one that HAOS supports). Air12Lite has 6 USB ports! It’s that simple.

Old thread but I thought I’d share my workaround.

Google Gemini provided me with the steps to connect to the wifi (but sadly not to the eth0 - wlan port). In any case here they are:

From the CLI “ha>” prompt:

1- type “login”
2- at the “#” prompt, type:
nmcli device wifi list
3- confirm your network is visible
4- connect to your network by typing:
nmcli device wifi connect “your ssid” --ack
5- provide your password

You will be connected and the network and password will be restored after a reboot.
