Version: unspecified (using KDE 4.5.1) OS: Linux Wireless networking is enabled by default and I have to turn if off after each reboot. I would like to disable Wifi permanently, or until I decide to turn it back on. Reproducible: Didn't try
This is a matter of taste. Several users would like to have wifi enabled by default. Anyway, you can disable wifi network in Plasma NM already. That will disable wifi in NetworkManager, but the transceiver will still be on. As far as I know most notebook only disables the transceiver if you use a hardware button. My two notebooks and my brother's work like that. Most notebook and netbooks's BIOS enable wifi transceiver inconditionally. Maybe you are lucky and your BIOS supports disabling wifi by default, both my notebooks' BIOS do not.
Lamarque, does this mean this wish cannot or will not be implemented?
I can add an option in configuration module to control the initial state for Wireless and Wwan (Mobile Broadband), but it will only set the state in NetworkManager, the transceiver will still be on and consumming energy. I do not know how much energy. This will take time since I am busy with other things.
I have found that you can configure the rfkill kernel module to set devices to a given state using the file /etc/modprobe.d/rfkill.conf. It may be at a different location or have a different name in your system (like /etc/modprobe.conf). To disable devices by default you can add the line below: options rfkill default_state=0 I think that is a better way to do what you want since Plasma NM does not have permission to edit system files. Also Plasma NM cannot reliably detect when the system has just booted, so adding the configuration like I wanted would not always work or would turn network off when that was not what the user wanted.
