8812au-20210629 VS openwrt-useful-tools

I've been trying for a few hours now to install drivers for a rtl8812au based usb wifi adapter (Edimax-7822ULC/UTC) on a nanopi r6c running kernel version 5.10.110. Zero luck with both the manufacturer driver for ubuntu and with an open source one-size-fits-all (https://github.com/morrownr/8812au-20210629). When running the manual install for morrownr's open source driver, I'm getting this error:

Is this a non-standart kali vm? If yes and you are learning, never sudo apt update/upgrade unless specifically told by your instructor. The adapter works for me with the drivers and intructions on github link

I have a dongle with that chipset, used it couple of times, worked fine. The driver I used is from here https://github.com/morrownr/8812au-20210629

Unofficially, the chipset itself seems to be the Realtek RTL8812AU chipset, which does have community support up to the current 6.1 kernel, but latest tested on Fedora is 5.11. (it will probably work, but honestly it's still a gamble). The work seems to mostly spur from the AUR repository, which links here.

As seen in the picture, every other ping seems to be about one second long and every other somewhat it should be. Pinging directly my Router via WLAN. There are different drivers available for the RTL8812AU, currently using this one: github.com/morrownr/8812au-20210629. The same issue persists using other drivers available. Power saving settings for the adapter are turned off, no effect.

The driver is available on github.

git clone https://github.com/morrownr/8812au-20210629.git

I had to reinstall a newer version of my driver ---> https://github.com/morrownr/8812au-20210629/issues/67

First you will need to find out which version you have. Version one or two (this one) will need this driver. For version three (this one) you will need this driver.
