Go to this link and see if your driver is there.

Turns out my card is a Realtek RTL8821CE. I think i found a zip file for the driver on Github but I'm not sure how to install it yet...

I cannot tell from your post if you had UEFI and Secure Boot turned off before or after the installation.  If you're not using the UEFI image file, those things need to be turned off before the installation.  Assuming you installed correctly, type the following into a terminal and share your results:

Code:

inxi -F
