if you sudo apt upgrade the firmware package for the q6a breaks wifi and i believe ethernet...

I do not have a concise fix for this i reflashed my device with the latest build after doing it originally to get wifi when validating the issue i had backed up the firmware etc for the default network drivers after upgrading broke the networking drivers had to restore firmware from previous build....

 

Would give a fix but aint that easy if you already upgraded you need to download the previous firmware put on usb stick and slap it on either that or figure out whats broken in the last one

 

this is kind of rambling but yeah just be careful upgrading 

can confirm:

I installed the latest image `Armbian_25.11.1_Radxa-dragon-q6a_noble_edge_6.18.0-rc6_minimal.img` and wifi works. After an `apt upgrade` wifi doesnt work anymore...

 

Solution:

same as on the Rock 5C

@just_facking_about type in `sudo dpkg-reconfigure aic8800-usb-dkms` and reboot the device

If you installed the Armbian 25.11.1 Edge Image the earlier post fixed the HDMI audio issue. However, if you upgrade with the command sudo apt update && sudo apt upgrade you will break both HDMI audio and WiFi.

Here is the new fix:

1. The Wi-Fi Fix (Rebuild DKMS)

Since the kernel updated, we just need to force the system to recompile the missing Wi-Fi driver for the new kernel version. Run this command in your terminal:

Bash

sudo dpkg-reconfigure aic8800-usb-dkms

 

Wait a minute or two for it to finish compiling. Your Wi-Fi will be restored upon your next reboot.

 

2. The HDMI Audio Fix (Restore Qualcomm Configs)

The HDMI audio broke because the system is now missing the Use Case Manager (UCM) profiles for the QCS6490 chip. We need to pull the newest configurations directly from the ALSA project repository and put them in the right folders.

Run these commands one by one:

Bash

# Install the base UCM configurations
sudo apt install -y alsa-ucm-conf

# Download the latest master branch configs to your temporary folder
cd /tmp
curl -sL "https://github.com/alsa-project/alsa-ucm-conf/archive/refs/heads/master.tar.gz" | tar xz

# Copy the specific Qualcomm configs and dependencies to your system
sudo cp -r alsa-ucm-conf-master/ucm2/Qualcomm/qcs6490 /usr/share/alsa/ucm2/Qualcomm/
sudo cp -r alsa-ucm-conf-master/ucm2/conf.d/qcs6490 /usr/share/alsa/ucm2/conf.d/
sudo cp -r alsa-ucm-conf-master/ucm2/lib /usr/share/alsa/ucm2/
sudo cp -r alsa-ucm-conf-master/ucm2/codecs /usr/share/alsa/ucm2/

# Restart your audio server to apply the changes
systemctl --user restart pulseaudio

 

Once you've run those, give your board a quick sudo reboot.
