Enabling/Disabling Wireless Radio. How?

citiz3n · 05-22-2008, 10:20 PM

Hi there guys,

Can anyone tell me whether there is any way to enable or disable the wireless radio in Linux via command line perhaps?

If tried doing some googling on this.. ended up with some saying that rfkill will do the trick. Can anyone here confirm this to me?

And secondly, can Rfkill be used to ALL wireless adapter or not?

Thanking you in advance.

I don't know about rfkill. It seems to me that it's a driver for physical button enabling/disabling wireless card in some laptops.
But you can treat the wireless interface as any other with ifup/ifdown. You can also switch off the radio with

Code:

iwconfig <interface name> txpower off

Though I'm not sure if it is exactly what you need.
Good luck.

ifdown <interface> will disable the wireless connection. If you want to completely turn off the transmitter, I'm not sure about that.
