8814au VS 8821cu

I ended up returning AWUS036ACM and buying AWUS1900 (based on Realtek chipset). Installed appropriate drivers https://github.com/morrownr/8814au and everything is working as expected! No issues so far. Working on both the Kali virtual machine and the raw Debian machine. Lesson learned - stay away from Mediatek.

I have same and got it to work using this driver on Github. The thing u/LoveFOSS recommended didn't work for me at all, but ymmv.

I've installed the driver for my NIC here

I'm trying to setup a local mumble server which clients can connect to over wifi, all provided by my AWUS1900 network card. I've gotten to the point where the NIC works with these instructions, and I setup a local AP following these instructions, but I cannot see the Mumble server running on the Pi3. I am able to connect to the hotspot but I can't ping any devices including the host of the whole server, strangely. When the pi is connected to ethernet to my local network, the mumble server works however.

However, if you're after long range or high speed with the Pi, and don't mind having to custom build a driver, I have this TP-Link Archer T9UH with the Realtek RTL8814au chipset. It needs this driver, which I was able to build by following the instructions on that page. It works like a champ, until there's a new kernel release, in which case it breaks until I rebuild that driver. It does however offer USB3 and 11ac, and has no trouble connecting and maintaining a high speed link (100+mbps) between where it lives in my RV parked in the driveway, and the AP in the back bedroom of my house. This is enough distance where the onboard Pi4 wifi could barely see my network and couldn't even sustain megabit speeds reliably.

I would recommend trying https://github.com/morrownr/8814au this driver, but honestly, the driver and that hardware are trash in terms of Linux support, and I’d highly recommend getting something from https://github.com/morrownr/USB-WiFi/blob/main/The_Short_List.md

It made no sense as to why it was scanning, it's my desktop adapter and only has to connect to a singular network. Anyway i figured it might've been due to roaming so i went and reinstalled the driver i use (i use an adapter with the rtl8814au chip and use this driver: https://github.com/morrownr/8814au), just to be sure i manually set the BSSID in the network settings.

Here's the driver.

If your linux kernel 5.8 or higher you can try to use this driver https://github.com/morrownr/8821cu

I managed to make my wifi to work thanks to the advice from u/marvelggg getting the drivers for my new wifi card here. https://github.com/morrownr/8821cu

I always had two problems on all linux distros (including previous versions of elementary): no wifi or sound. The wifi driver needed is the rtl8821cu realtek driver. I followed the instructions for 'Ubuntu and derivatives' in the README.md but got this error (These exact steps worked ine in the previous version of elementary):

Hi everyone! My rtl8821cu wifi adapter doesn't work on Artix Linux (runit). I've installed this driver via dkms, I also tried to install rtl8821cu-dkms-git package from AUR but it still doesn't work.
