This driver is for the AIC8800D80 chipset, supported by devices such as the Tenda U11 and AX913B.

Added support for devices with Vendor ID 368B (tested).

Tested on Linux kernel 6.16 with Ubuntu 25.04 and 6.1.0.27 with Debian 12.

Bluetooth not working.

I did not develop this software, The code is sourced from the Tenda U11 driver. I only made some modifications to the code to adapt it to newer kernel versions. Apart from compilation issues, I am unable to address other problems.

Before installing the driver, delete all aic8800-related folders under /lib/firmware. Using an incorrect firmware version may cause the system to freeze.

Copy the aic.rules file to /lib/udev/rules.d/:

sudo cp aic.rules /lib/udev/rules.d/

Copy the aic8800D80 folder from ./fw to /lib/firmware/:

sudo cp -r ./fw/aic8800D80 /lib/firmware/

Change to the drivers/aic8800 directory:

cd ./drivers/aic8800

First, compile the driver:

make

Then, install the driver:

sudo make install

For any kernel updates, you'll need to reinstall the driver:

make clean
make
sudo make install

After installation, load the driver with the following command:

sudo modprobe aic8800_fdrv

Check if the module is loaded correctly:

lsmod | grep aic

You should see output similar to:

aic8800_fdrv    536576  0
cfg80211        1146880 1   aic8800_fdrv
aic_load_fw     69632   1   aic8800_fdrv
usbcore         348160  10  xhci_hcd,ehci_pci,usbhid,usb_storage,ehci_hcd,xhci_pci,uas,aic_load_fw,uhci_hcd,aic8800_fdrv

After that, plug in your USB wireless network card.

To check if the Wi-Fi interface is recognized, run:

iwconfig

If the device is still not active, check the kernel logs for any errors related to the driver:

sudo dmesg
