Wifi Adapter suddenly not working

[authenticastrology]

Hello everyone. Suddenly today, out of the blue and for no reason, my wifi adapter stopped working on Linux Mint 20.2. I have seen this problem listed before and so I am posting the requested information after using the following commands:
inxi -Fxz

rfkill list

Here is the output of the former:

The latter returns nothing

Hope someone can help. Desperately need my wifi for work and have no wired connection
