Attempt 2: Use my iPhone’s Personal Hotspot Unfortunately, my newly installed Ubuntu doesn’t have gcc nor make - which the install script included in the download required. While the installation procedure for Windows and Mac is as simple as running some executable, the Linux version comes in source code, so I need to build it myself. The first thing I tried was to download the RTL8811CU chipset from Realtek’s website from my MacBook, copy it to an USB flash drive, eject it, plug it into my Linux desktop, and try to install it from there.

🙄 this is counter-productive for me at the moment as I need to somehow get an internet connection in the first place. Of the many articles on stack exchange and Ubuntu forums, the “proper” way to install these essential drivers is to already have an internet connection and use apt install to install more packages. Then in the solution section, I go over the exact steps I took to get internet working. I will talk about the troubles I went through in the next section. So, I use one of the cheap USB WiFi adapter I bought from Amazon. Also I live in a place where there is no ethernet ports, which makes the process more difficult. Unfortunately, my PC motherboard (Gigabyte Z370) does not have any built in wireless or bluetooth chipset, and somehow I need to get internet working. Recently I did a fresh install of Ubuntu (actually Kubuntu) 20.04 on my desktop PC.
