TP-Link AX1800 Archer TX20U (RTL8852AU) with Linunx (Mint)

Note to self:

### Secure Boot needs to supposedly be disabled, it's off on my device anyways
### else you would have to do some keying stuff ;-)
mokutil --sb-state

### Download git repo
mkdir TX20U
cd TX20U
git clone https://github.com/morrownr/rtw8

sudo dkms install .

### Blacklist modules in stock Kernel

### Reboot
reboot


Why? Atheros ath10k card in this Lenovo V15 ADA does not work properly with my FritzBox 7390 - constant disconnects and very slow uploads. (Problem is supposedly in the firmware and I was just sick of debugging it.) New Router: 200+ Euros, new USB WiFi Stick: 15 Euros. And because I can. ;-)
