Tl-wn422g Atheros Linux Driver

How to Install TL-WN422G Atheros Linux Driver

If you have a TP-Link TL-WN422G wireless USB adapter and want to use it on your Linux system, you may need to install a driver for it. The TL-WN422G uses an Atheros chipset that is supported by the ath9k_htc kernel module, but you also need to install the firmware for it.

In this article, we will show you how to install the TL-WN422G Atheros Linux driver on Debian-based distributions, such as Ubuntu, Mint, or Kali. We will also show you how to check if the driver is working properly and how to configure your wireless interface.

Step 1: Install the firmware-atheros package

The firmware-atheros package contains the firmware files for Atheros wireless devices, including the TL-WN422G. You can install it from the official repositories by adding a \"non-free\" component to your /etc/apt/sources.list file, for example:

# Debian 11 \"Bullseye\"

deb http://deb.debian.org/debian/ bullseye main contrib non-free

Then, update the list of available packages and install the firmware-atheros package:

sudo apt update

sudo apt install firmware-atheros

If you prefer to use open firmware, you can also install the firmware-ath9k-htc package instead:

sudo apt install firmware-ath9k-htc

Step 2: Connect the device to your system

After installing the firmware package, you can connect the TL-WN422G adapter to your system. The ath9k_htc kernel module should be automatically loaded for supported devices. You can check if the module is loaded by running:

lsmod grep ath9k_htc

If you see some output, it means the module is loaded. You can also check if the device is recognized by running:

iwconfig

You should see a wireless interface named wlan0 or something similar. If you don't see any wireless interface, you may need to manually load the module by running:

sudo modprobe ath9k_htc

Step 3: Configure your wireless interface

Now that you have installed the driver and connected the device, you can configure your wireless interface as appropriate. You can use various tools to do this, such as iw, iwconfig, nmcli, nmtui, wpa_supplicant, or network-manager. For example, to scan for available networks using iw, you can run:

sudo iw wlan0 scan

To connect to a network using wpa_supplicant, you can create a configuration file with your network credentials, such as:

# /etc/wpa_supplicant/wpa_supplicant.conf

network={

ssid=\"YourNetworkName\"

psk=\"YourNetworkPassword\"

}

Then, run wpa_supplicant with your configuration file and interface name:

sudo wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

To obtain an IP address using dhclient, you can run:

sudo dhclient wlan0

You should now be connected to your wireless network.
