I'm trying to debug a buggy wireless card and would like to force my Linux computer to connect using one of the g-band channels. How can I achieve this?

1 Answer 1


'G-Band channels' are the same as b/n. If you want to connect using G only you could use iwconfig like so iwconfig eth0 freq 2.422G

  • I've disabled NetworkManager, but whenever I run this command (on the wlan0 interface), I get SET failed on device wlan0 ; Device or resource busy. Is there a way to find out what's keeping it busy?

  • I believe you just don't have permission to execute that command. I found adding "sudo" in front worked for me "sudo iwconfig wlan0 freq 2.412" executed without that error.
