Radxa Rock 3C v1.4 wifi not working

ROCK 3 Series
1

Is the board version v1.4 (blue PCB) using AIC8800 wifi+bt chip?

I’m using the latest Debian build rock-3c_debian_bullseye_xfce_b39.img.xz

Here’s ifconfig, looks to me all RX packets are dropped.

Thank you - will give it a go. But I can’t see any activity in that GitHub repo? I guess you made changes to the AIC8800 WiFi / BLE driver and firmware, I want to look into it and see if I can patch it for the Radxa Zero3W which ships with the same WiFi / BLE chip too.

Hi
We install AIC8800 driver by dkms, the zero 3w new image was suppord AIC8800,you can try use new image.

I can confirm the official images are working both WiFi and Bluetooth.

But the AIC8800 WiFi chip does not work with my Unifi AP U6-LR which has WiFi 6. It’s fairly well documented that the Unifi WiFi 6 APs do not work with certain WiFi6 client chips and the behaviour is strange: It can ping both internal IP and Internet IP, but it does not sustain the connection, but it will not disconnect. I cannot even ssh to my board.

But I do not have another WiFi 6 AP / router to test if AIC8800 works with another WiFi

I have found if you do a direct connect to your network and do a complete update the wireless connection will begin to work. You can get then unplug the wired connection. I did this o n two 4C+s.

Is there a version of Debian headless of b42 which has WiFi working out of the box? By the way why can’t I see builds after b39 in your GitHub?

No, b42 is listed at github, you can find it at bottom of that page.
