From my testing, it appears the change made using iwconfig will remain until you switch wireless networks or until your device is idle for ~30 seconds.
Thanks for help...
But it's looks like not working...
when i switch off power saving by UI
i get:

Code:
PING n900 (192...) 56(84) bytes of data.
64 bytes from n900 (192...): icmp_seq=153 ttl=64 time=2.54 ms
64 bytes from n900 (192...): icmp_seq=154 ttl=64 time=2.23 ms
64 bytes from n900 (192...): icmp_seq=155 ttl=64 time=2.51 ms
When I switch on power saving by UI i get:
Code:
PING n900 (192...) 56(84) bytes of data.
64 bytes from n900 (192...): icmp_seq=1 ttl=64 time=2339 ms
64 bytes from n900 (192...): icmp_seq=3 ttl=64 time=1340 ms
64 bytes from n900 (192...): icmp_seq=4 ttl=64 time=1582 ms
When I use "iwconfig wlan0 power off"
iwconfig say that Power managment is OFF on wlan0 but:

Code:
PING n900 (192...) 56(84) bytes of data.
64 bytes from n900 (192...): icmp_seq=18 ttl=64 time=958 ms
64 bytes from n900 (192...): icmp_seq=19 ttl=64 time=1985 ms
64 bytes from n900 (192...): icmp_seq=20 ttl=64 time=2069 ms
64 bytes from n900 (192...): icmp_seq=21 ttl=64 time=1070 ms
Any idea... ?


Edit: It's work when you use this command in Xterminal in device not via ssh as i have done it before...
