I am experiencing some wifi troubles, and would very much appreciate some advice for my situation.
I am currently running ubuntu 20.04 on dual boot.
I use a dual monitor setup, but this morning ubuntu could not detect the second monitor.
After finding some suggestions to update my Nvidia version, I ran :
sudo ubuntu-drivers autoinstall
sudo apt update and sudo apt upgrade -y This changed my Nvidia driver from version 460 to 470. Also changed my kernel from 5.13.0-27-generic to 5.13.0-28-generic.
Here's some of my system details:

After rebooting, the second monitor was detected, but I had lost all wifi functionality. I can reboot into an old kernel version and the wifi there still works.
lshw -C Network still detects the Wirless Interface:

Finally I have seen this post:
Wireless adapter unclaimed after update and reboot, however after switching to the kernel with wifi and running sudo apt update, then sudo apt install linux-modules-extra-5.13.0-28-generic returns
