I got a new laptop yesterday with Windows 10 pre-installed, which I then upgraded to Windows 11. I installed Ubuntu 20.04 via USB (I was prompted to enter a MOK key. Upon rebooting after the Ubuntu installation, I was taken to the blue MOK screen, but the laptop froze, and I had to force-shutdown. Thereafter, I was not prompted to enter my MOK key again.)
I was able to connect to the internet via a wired connection, but not via WiFi. I have read multiple posts on similar issues with the WiFi adapter not being detected, and ended up implementing the solution in this post. I had to disable the Windows SecureBoot via BIOS in order to do so. I get the following output after installing the GBE Ethernet LINUX driver r8168 for kernel up to 5.6 driver:

After rebooting, I am still unable to connect to WiFi as the WiFi adapter is not found:
Any advice/help here would be much appreciated!
