Options for RTL8192EU wifi adapter?

I have a TP-Link TL-WN822N v5 wifi adapter, which uses the RTL8192EU chipset. After months of noticing problems with it, but also feeling like it worked better in Windows than in Linux, I've confirmed that it's known to not play nicely with the normal drivers that come with Linux.
The manufacturer offers drivers but they don't work with any Linux kernel past 4.9 and I'd rather not be stuck on MX-19 forever.
What are my options?

Take a look at the drivers here.

This site is based on a newer driver version and works with our newest kernels.

Are there any solutions that don't involve downloading source code and compiling it myself? that has always been a crapshoot for me with more failures than successes, often due to unresolvable dependencies.

From here:
https://www.tp-link.com/ca/home-network ... tl-wn822n/
That's a b/g/n adapter and often the drivers will default to the n protocol. In theory the n protocol is the fastest with the widest range, but in practice it is so susceptible to interference that it is useless. You should either configure your router to only broadcast in g or use Network manager in the panel to do the same.

Don't have a RTL8192EU device, but just to see what happens I tried the instructions in Tim's link in a Live session of MX-23.6.ahs,
OOTB everything appears to be already installed (i.e. no dependency issues).
Easy install, 3 cli commands.

The instructions in Tim's link skipped a couple of steps, like the "git clone" and "cd" parts, but I was able to mix instruction information from both links to figure out what to do. A couple of errors popped up during compilation/installation and the wifi card didn't work any better. Thinking that I mgiht need to restart the computer for the changes to take effect, I did that, and the card still didn't work any better. After a few other dead ends, I tried going back into the source code directory and just running install_wifi.sh again for sh!ts and giggles, not really expecting it to work, but for some reason, it did work this time. *shrug*
I think the trick is to restart the computer after installing DKMS but before trying to compile and install the drivers.
Anyway, thanks for the help!
