I have been using Ubuntu 18.04 for about a month now on a Dual Boot system. I've had WiFi issues in the past, but nothing that couldn't be fixed by a reboot. However, recently I have not been able to connect to WiFi at all.
On typing lspci, I get the following:

As you can see, the computer uses Intel WiFi drivers. Sometimes, they don't show up at all with this command.
I've tried all the steps on this answer without much success: No WiFi Adaptor found in Lenovo X1 Carbon Generation 7
I just installed Ubuntu 19.10, hoping the problem would be solved, but that didn't help either. I am currently on 19.10
I am able to connect through USB tethering though, and the WiFi has worked for 5-10 minutes these past few days.
Also, WiFi works just find when I boot into Windows.
Any help would be greatly appreciated!
Edit 1: Here is the output of sudo modprobe iwlwifi && dmesg | grep iwl
The output is too long, so here are the opening and ending lines:
