My laptop has integrated Mobile Broadband so it can get internet from cell phone waves when I'm away from home. It also has WiFi so it can get internet by connecting to my wireless router when I'm at home.
I have a Lenovo laptop and when I first got it it had Windows installed. Using Windows I was able to selectively turn on/off the "WiFi" antenna and/or the "Mobile Broadband" antenna. I could have both on, both off, or one on and one off.
Using my laptop's Fn keyboard shortcut to activate the antennas in Ubuntu appears to be an all on or all off action. Battery life when using Ubuntu is not the greatest. So I was thinking it might be helpful to make sure that unnecessary antennas are not on when they don't need to be. So when I am away from home and using Mobile Broadband is there a way I can disable the WiFi antenna, and vice versa for when I am at home?
