Hi, thank you for sharing this awesome work. My problem is that I checked the driver was Installed well, but my wifi is not turning on. Could you help me what I can do for next?

Here is my environment information.

Hi @yosungho

Let's see what is inside that adapter before continuing. Please run and post the results of the following:

$ lsusb

Hello @morrownr

This is what I got. $ lsusb Bus 002 Device 002: ID 2109:0812 VIA Labs, Inc. VL812 Hub Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 006: ID 046d:c52b Logitech, Inc.

That confirms this is the correct driver.

Time to do some more digging. Can you run and post the results of the following:

$ sudo uname -a; mokutil --sb-state; rfkill list all; dkms status; iw dev

This is the results: $ sudo uname -a; mokutil --sb-state; rfkill list all; dkms status; iw dev Linux AD02019911 5.13.0-51-generic #58~20.04.1-Ubuntu SMP Tue Jun 14 11:29:12 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux SecureBoot enabled rtl8814au, 5.8.5.1, 5.13.0-51-generic, x86_64: installed

My next recommendation is for you to go into the bios and turn off SecureBoot so as to see if that may be causing a problem.

dkms is telling us the driver is installed but no wifi interface is showing.

yosungho commented 2 years ago

It works after disabling SecureBoot. I appreciate you.
