ALFA USB Wifi adapters

Finally found a solution - this from Rokland.com

As you may have noticed, the latest Linux kernels have caused a large amount of wireless USB adapters to lose monitor mode support. Thanks to a diligent community of Wi-Fi enthusiasts a work around has already been found, so that you no longer have to downgrade to an older kernel.

You can find more detailed instructions on the driver install here:
GitHub - aircrack-ng/rtl8812au: RTL8812AU/21AU and RTL8814AU driver with monitor mode and frame injection

Tested and working method as of AUG 2024.

If you have already attempted to install the driver first uninstall the driver. This can be done by opening Terminal and navigating to the directory the install was performed in. Then run the following command:

sudo make dkms_remove

Next we usually suggest making sure your distro is up to date.

sudo apt update && sudo apt upgrade

Next we will install some pre-requisites that are sometimes not included in every distribution of Linux by running the following commands in Terminal (*Note - This is mainly for Ubuntu users, Kali usually has these pre installed.)

sudo apt-get install dkms

sudo apt-get install make

sudo apt-get install iw

sudo apt-get install git

Finally we will download and install the driver.

git clone -b v5.6.4.2 GitHub - aircrack-ng/rtl8812au: RTL8812AU/21AU and RTL8814AU driver with monitor mode and frame injection

cd rtl*

sudo git checkout 63cf0b4

sudo make dkms_install

Hope that helps someone

Or, just use properly supported wifi adapters and not buy garbage realtek chipset adapters.

Geez guy I think everyone gets it. It’s not really conducive to fix a problem by saying don’t purchase something you already bought and get the better one. A single or maybe two mentions of using a different adapter probably would have been enough

My Wifi adapter will go into monitor mode. AngryOxide will do that… but it doesn’t seem to work, at all. Even with turning off the NetworkManager service. Does anyone have an idea of a cause of such a problem?
