Is there a command to turn off my Broadcom wireless card to save power. In Apple, the have an Airport off listing under the airport menu, Is there something for Fedora?

Hello duke11235

As no one else has answered you can have my thoughts. If you right click on the NetworkManager icon in the system tray there is a disable wireless.

My broadcom happily reconnects if I use "Enable Wireless" after this.

I'm not sure just how much power it saves though.

I'll be interested if you get any results to hear what they are.

If you want to turn you wireless kind of permanently, then disabling it in the BIOS - if your laptop has that option - clearly saves the most power. The drawback is, that you would have to reboot in order to go wireless.

Powertop Results

It appears to have lowered power intake (for me) from 18 to 16 watts. I'm guessing that'll get me 20-30 more minutes of battery
