Randy Ciwyll’s repository has the solution that worked for my system (Linux Mint 18.3 Kernel 4.10). As chili555 guessed, my device is the rtl8822bu. And yes, I have found that I need to reinstall the driver every time I get an applicable update.
sudo apt update
sudo apt install dkms bc git
git clone https://github.com/cilynx/rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959
sudo dkms add ./rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959
sudo dkms install -m rtl88x2bu -v 5.3.1
sudo modprobe 88x2bu
