Airplane mode

Airplanes probably don't actually need you to turn your wireless off.(more information please?) However, if you find it necessary you may apply one of the following two methods.

Method 1: Disable wireless temporarily until next reboot

This method will turn the radio off only until the next reboot. So there is an issue when during a flight your XO is turned off. Naturally, the 802.11 wireless radio does not interfere with the aircraft controls, and you can simply turn your XO on, wait until it boots and disable the radio then. If you want to avoid this, you can disable the radio when still on land and keep your XO turned on or suspended to save power. Alternatively you can disable the radio permanently as described in Method 2.

• To turn the radio off go to Terminal activity and type:

sugar-control-panel -s radio off

• To turn it back on go to Terminal activity and type:

sugar-control-panel -s radio on

Method 2: Disable wireless permanently

This method will keep the radio off even after reboots. Therefore you can turn the radio off when on land and turn the XO off as well until you need to use it. When landed you can recover the radio back to normal.

• To turn the radio off go to Terminal activity or Virtual Terminal and type:

rmmod usb8xxx

[rmmod: command not found]

mv /lib/firmware/usb8388.bin /lib/firmware/usb8388.bin.quiet
#no need to reboot

• To turn it back on go to Terminal activity or Virtual Terminal and type:

mv /lib/firmware/usb8388.bin.quiet /lib/firmware/usb8388.bin
rmmod usb8xxx
sleep1
modprobe usb8xxx
#might need to reboot
