Airplane mode

Airplanes probably don't actually need you to turn your wireless off. But to do so on the XO-1 go to a Developer Console, or the Terminal Activity and issue the following commands:

Disable wireless until next reboot

This method will turn the radio off only until the next reboot. Naturally, the 802.11 wireless radio does not interfere with the aircraft controls, and you can simply turn your XO on, and when it boots you can disable the radio. If you want to avoid this, you can disable the radio when still on land and keep it turned on, or suspended to save power. Alternatively you can disable the radio permanently as described further on.

• 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

Disable wireless permanently

This method will keep the radio of even after reboots. Therefore you can turn the radio off when on land and turn the XO off until you need to use it. When landed you can recover the radio back to normal. modprobe usb8xxx

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

rmmod usb8xxx
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
