[solved] WiFi Adapter Driver - Old Problems Arise Once More

[Zoltan955342]

Turns out my problem was a simple spelling error. I was typing "rt18821ce" when I needed to be typing "rtl8821ce". Sorry for the wasted post and stupid mistake. Don't forget to check your spelling, guys. I'm feeling pretty dumb right now.

So I ended up trying out a few different distros on my laptop and then eventually ended up taking a long break from playing with Linux. I'm now back to Linux Mint, this time probably for good because it was my favorite, but I'm having a problem with my wifi again. The issue is a missing driver for my laptop's internal wifi adapter. I went back to this thread where I previously found the solution to my problem. The problem now is that when I run the git clone command posted by JeremyB, the repository to which it refers is returned as not found.

I need a new solution to my wifi driver issue. Can someone please give me a hand?
