How to change wlan0's channel

  • 772

When setting the channel to wlan0, I get an error:

SET failed on device wlan0 ; Device or resource busy.

I tried to shutdown wlan0 by:

sudo ifconfig wlan0 down

and wlan0 did not appear in the ifconfig result, but I still get the error when I use this command to switch channels:

sudo iwconfig wlan0 channal 1

The funniest thing is I just used this method to change channal from 4 to 6, and now I want to change the channal from 6 to 1, but I can't finish it. Did I miss something?

command-line
