Laptop won't recognise wifi card anymore

Laptop model: Dell latitude E6420
Ubuntu version: 18.04.2 LTS
My wifi was working completely fine up until last night. Now, my laptop says "no wifi adapter found" and therefore won't let me connect. I've tried turning the power off and restarting it many times. I have tried some suggestions that I've found on here and none of them work.
However my computer is recognising the card as it shows up when I use lshw -C network and lspci. It shows up in the terminal but the setting application says it's not there. (I was going to add the output but I don't have enough reputation to add images here yet.)
What can I do?
Thanks.

There have been reports of people having problems when moving from the 4.15 to 4.18 Linux kernel with some Dell hardware. You'll want to manually downgrade your Linux kernel, the easiest way to do that is using the Ubuntu Update Kernel Utility (UKUU)
sudo add-apt-repository ppa:teejee2008/ppa
sudo apt update
sudo apt-get install ukuu
Now launch the ukuu app and select one of the 4.15 kernels to downgrade to.
