I have an intel wireless card (4965 AGN) and am running the kernel26zen-git kernel.
When I am on the wireless network in school, for some reason my wireless card is in constant activity from requests from other computers, and my battery is suffering severely for it. Is there a way to prevent this? Is my card being treated as a router?
Power saving from iwconfig doesn't work properly:
[root@redscare redscare]# iwconfig wlan0 power on
Error for wireless request "Set Power Management" (8B2C) :
SET failed on device wlan0 ; Operation not supported.
Thank you for your help.

See comment 8:
We now know that both 3945 and 4965 power-save don't work, due to unreliable save/restore of device's SRAM data on host DRAM. Reinette's patch disables power-save now for 3945 (it has already been disabled for 4965 for months).

Thanks painless. I guess another question would be whether it's possible to at least ensure that my computer isn't being treated as a router by other computers constantly as a different power saving option?

As long as you don't have more than one network interface active at any one time, then it cannot be routing. So you should bring down any unneeded network interfaces. Other than that, a properly configured firewall would help. It's always a good idea to have a firewall running.
