rtl8812au VS rpi-source

Hello thanks everyone for help I recently instilled Ubuntu Linux (version 22.04.03 LTS) and my Archer T2U Nano Drivers were not recognized since I am new, I looked for tutorials and they all assumed you have a working internet connection so can just download the git hub online. Since I don't have access to a Ethernet or anything else (tried Samsung tethering did not work) I am out of option tried installing the GitHub bit am major noob had no idea what to do. I think this is the right GitHub - aircrack-ng/rtl8812au: RTL8812AU/21AU and RTL8814AU driver with monitor mode and frame injection for anyone that can help guide me through an installation without internet thank you very much.

git clone -b v5.6.4.2 https://github.com/aircrack-ng/rtl8812au.git && cd rtl* && sudo make && sudo make install

Have you tried the aircrack driver? And what is the output for lspci and lsusb

Probably you need to install the driver for your wifi card. Just follow the instructions of this link to install the driver and then reboot the OS.

sudo apt -y install dkms git build-essential libelf-dev linux-headers-`uname -r` && reboot git clone https://github.com/aircrack-ng/rtl8812au.git && cd rtl8812au && sudo make dkms_install && reboot Plug in wifi card and hack away :)

I'm using Arch Linux (6.1.15-1-lts) with "TP-Link Archer T2U PLUS (RTL8821AU)" and these drivers (I have also tried using these drivers. I'm using an Ethernet connection and I've setup a hotspot in my PC (to use it with my android devices) (I don't have a Wi-Fi router at the moment, sorry). I'm getting serious ping losses in my android phone. Messaging apps are taking forever to send/receive messages (but not when using hotspot from Windows 10).

https://github.com/aircrack-ng/rtl8812au asumen that you already see this link only for reference, in theory if it works with any of your rt88xxau it will be work with the newest alpha Wi-Fi adapters such as AWUS036ACH.

You can use apt full-update and that should push you to the correct kernel. This page has also helped me in the past.
