Key	Description

package filename	`ccr_wifi_power_mode-xyz.deb`
configuration	none
cron job	`/etc/cron.d/ccr_wifi_power_mode`
script	`/usr/bin/ccr_wifi_power_mode.sh`
examples	`sudo ccr_wifi_power_mode.sh`

The WiFi adapter has 3 different power modes:

active power
low power
extreme low power

The default power mode when the adapter starts is "extreme low power". The ccr_wifi_power_mode.sh script automatically changes the adapter to place it into "active power". On a BeagleBone with no wireless device, this script does nothing.

To install:

sudo dpkg -i ccr_wifi_power_mode-*.deb

Then either reboot the device, or manually run the script:

sudo ccr_wifi_power_mode.sh
