Tp-Link TL-WN823N V1 [15/19] Use the command line

Use the Command Line

You can use commands to manage your wireless setting in Linux. Here we use the

interfaces for Kali 2018.1 as an example for illustration.

1. Identify the Device

Inert the USB wireless adapter, and run the following command to check if the adapter is

identified.

$ lsusb

2. Create the Interface

Run the following command to check if the wireless network interface is created.

$ ifconfig

3. Change the Interface Status to Up

Check if the WLAN interface is up. If not, run the following command. Here we use wlan1

as an example.

$ ifconfig wlan1 up

If it failed to change to up, run the following command to set the state again.

$ rfkill unblock wifi

$ ifconfig wlan1 up

4. Start wpa_supplicant in the background

Run the following command:

$ wpa_supplicant –Dnl80211 –iwlan1 –c ./ wpa_0_8.conf -B

Note: wpa_0_8.conf is a file in the current driver directory, go to the driver directory when

running the command.

If the command above is not effective, run the following command to end the

wpa_supplicant procedure and then run the above command again.

$ killall wpa_supplicant

If your Linux kernel does not support 802.11, run the following command.

$ wpa_supplicant -Dwext -iwlan0 -c ./wpa_0_8.conf -B
