I have a AR5413 wireless card,and the driver is Madwifi-r3314.I want to know how to enable the power saving feature using Madwifi.When I use the comand "iwconfig ath0 power saving 1(or other number)", it said that "
Error for wireless request "Set Power Management" (8B2C) :
SET failed on device ath0 ; Operation not supported."
How can I enable the power saving mode?
Thank you for your help!
