How to Change a Wireless Card Channel in Linux

Save

Working with network connections on the command line is often seen by beginning Linux users as an intimidating process. In fact, there are dozens of tools that make it easy to do in the GUI but the command line interface is still the quickest. Changing the channel of your wireless card will take you no more than the time it takes you to type a few words.

Things You'll Need

  • Wireless tools package installed
  • Open a Terminal window.

  • Type ifconfig and check what your wireless interface is called. It is probably called wlan0 or wlan1. Make note of its name.

  • Type iwconfig wlan0 channel #
    where wlan0 is the name of your interface and # is the channel number you wish to switch to. After you have run that command, the channel is set to the new number of your choosing.
