Driver crashes PC on Arch Linux 6.10.8-arch1-1

[c0ncatenate]

Hello,

I am currently on Arch Linux kernel 6.10.8-arch1-1 and I have an Alfa AWUS036ACS AC600 Wireless Adapter. DeviWiki suggests that my adapter uses the RTL8812AU driver. I've installed the driver using the install.sh script provided and everything installs as intended.

The device seems to recognize the driver and the LED lights up. I can see it in my WiFi devices list. However, when I try to use an app like Wireshark, it crashes my entire PC. When I try using tools such as sudo airodump-ng wlan1, it is unable to find any APs around me. I believe the driver is not updated to the latest kernel on Arch and it's breaking something in the background. I have also tried the driver from Aircrack-NG but it doesn't work for me either. If anyone has an updated driver/kernel that I can use or a workaround to get it working, please let me know. I am devastated. :/

If you need any additional information from me, I'd be happy to provide. Thank you!

Hi @c0ncatenate

I think you need a different driver. Run the following and post the results:

$ lsusb

Alfa AWUS036ACS AC600 Wireless Adapter

This adapter uses the rtl8811au chip. Options for drivers:

https://github.com/morrownr/8821au-20210708
morrownr/8821au-20210708#133

Note: The second driver has been used for dev to get a good standards compliant driver in the kernel. The driver is currently under review and should be in an upcoming kernel such as 6.13. Remember to uninstall any previously installed drivers.
