No WiFi with TP-Link AC600

[T1moschenk0]

TP-Link AC600 Archer T2U nano WiFi USB adapter driver is correctly installed (sudo dkms status, LED blinking) in my ASUS notebook running Kubuntu 23.10. However, no WiFi connection is detected.
Any help, please ?

What WiFi are you wanting to see/connect too? Is it your local (home) network?

driver is correctly installed

Using what instructions or source? There may be multiple versions or builds of the driver code

What does lsusb show for your adapter?

If no access points are displayed, then the driver is not working.

The WiFi I'm trying to connect to is local home.
Instructions were:
sudo apt install dkms git build-essential libelf-dev linux-headers-$(uname -r)
git clone https:// github.com/aircrack-ng/rtl8812au.git
cd rtl8812au/
sudo make dkms_install
Then
sudo dkms status
8812au,5.6.4.2_35491.20191025, 6.5.0-26-generic, x86_64: installed

I don't believe that the aircrack-ng 8812au driver is the correct one for your 8811au, though this is VERY confusing, and at some points in the past, and on older kernels, this *may* have worked.

THIS is the one I would have suggested, as it explicitly mentions 8811au. No idea if it will work.

Both this and the aircrack are derived from the same ancient Realtek code(s), since Realtek are.......crap when it comes to Linux, even if they did toss out some code at some point.

You may want to completely uninstall the aircrack driver, and try this one.
I have used various morrownr drivers for different devices in the past, and in my own experience, they mostly worked, while the aircrack ones usually didn't.

No, it didn't.
