Title: Enabling Wireless Card Power Managment
Post by: dvdrw on February 03, 2005, 01:53:08 pm

laze, have you thought about providing an option (or enabling by default) power management for the wireless card in the lan/network panel (wireless tab)?  I've played around with this, and it seems to help battery life noticeably with my DLink/SanDisk CF 802 cards (both are Prism-based cards.)  I am not sure about compatiblity with other cards though.

you can enable powersave mode at the command line by entering:

   iwconfig eth0 power on

to make powersave mode always enabled, I modified "/usr/bin/network.py", and searched for 'case "$ADDRESS" in' (should be around line 68), and inserted this string before the case statement:

   IWCONFIG="power on"

seems to work great, and it does seem to help improve battery life with the wireless card.

just a thought...!

I already use the LP Socket Card, so maybe this will help even more.

Thanks for the tip.

I found that string two times in the pythin script. I put the power stuff right before each of the two repetition. Right?
