Hi,

By "the adapter is recognized by my system" do you mean your T2U Nano shows up when running commands like "nmcli" or "iw list"?

The driver is loaded correctly:

$ sudo dmesg | grep 8812au
[ 2347.697150] RTL871X: rtl8812au v4.3.8_12175.20140902
[ 2347.697258] usbcore: registered new interface driver rtl8812au
 

T2U Nano doesn't shows up when running "nmcli". 

  @bna 

Ok. I've just tested this aircrack-ng/rtl8812au driver myself with an Archer T4U V2 and Ubuntu 24 and what I am seeing is that the T4U shows up in the GUI but it's scanning forever and not finding any Wi-Fi networks. Is that also what you are seeing with your Archer T2U Nano?

So I think this particular driver somehow doesn't work with Ubuntu 24 and you might want to look for another driver, perhaps this one https://github.com/morrownr/8812au.

By the way, is the Archer T4U you mentioned previously a V2 or V3? Only the Archer T4U V2 (and probably also V1) can use rtl8812au drivers. The Archer T4U V3 uses the rtl8812bu, for which drivers have already been built into newer Linux kernels (starting with version 6.2 I believe).

Exactly! The adapter appears in the GUI, but it keeps scanning without finding any Wi-Fi networks.

The GitHub repository you shared redirects to: https://github.com/morrownr/8812au-20210820. Is it safe to install? 

Although it was made in 2024, it still states "Ver: 1.0" in the box.

This driver is no more or less safe to install than the other one you tried previously. It's always the same story. Realtek (the company who makes the Wi-Fi chip) originally made a driver for Linux, but stopped developing the driver further several years ago, which lead to the driver becoming outdated and incompatible with newer Linux kernels. However, Realtek made the source code for the driver available to the public and this allowed some independant developers to modify the driver to work with newer Linux kernels.

Out of interest I've just installed the driver from https://github.com/morrownr/8812au-20210820 in my Ubuntu 24 and my Archer T4U V2 (the one with the rtl8812au chip) seems to work fine with it, so I think the driver should also work fine with the rtl8811au chip in your T2U Nano.
