[SOLVED] Connect to Wi-Fi network with my TP-Link Archer T3U AC1300

Hello, originally I didn't plan my desktop PC to work with wireless connections. But because destiny is a little smartass, I don't longer have access to my Ethernet cable and so I need to use Wi-Fi. For this, I bought a TP-Link Archer T3U AC1300 that could (according to what I did read) work with Linux with the correct drivers.
Sadly, despite trying to install several open-source drivers (this one: https://github.com/RinCat/RTL88x2BU-Linux-Driver or the rtl8822bu-dkms AUR package), I can't get connected to my home Wi-Fi connection. I am a bit lost...

However it seems like my computer detects very well the USB device according to lsusb -v :

        bInterval               0

Also, I feel like my NetworkManager daemon is not prepared yet to use Wi-Fi because the GUI doesn't show any "wireless network detection" button nor window : instead of this, I need to create a Wi-Fi connection manually, to enter the connection ID etc. I don't think it's working.

Thanks in advance.

Re: [SOLVED] Connect to Wi-Fi network with my TP-Link Archer T3U AC1300

https://aur.archlinux.org/packages/rtl88x2bu-dkms-git
After installing that (and removing the other drivers), post a complete system journal if you've still problems

sudo journalctl -b > /tmp/journal.txt # you can then usb walk that file to a system w/ internet

At the begin my Plasma desktop lagged a lot but the driver finally started to work by itself and now I can use my Wifi device. Thanks a lot!
