Disabling wlan power management

Disabling power management on a wlan device is easy in the one-off case:

# /sbin/iwconfig wlan0 power off

However, pm-utils will re-enable power management when certain events occur, such as disconnecting AC power. To unconditionally keep power management off, create /etc/pm/power.d/wireless as an executable script with the following contents:

/sbin/iwconfig wlan0 power off

You'll only receive email when they publish something new.
