Use the power management of the wireless card. You can tell it to shorten
the window it is allowed to use, and it will use less power accordingly.
Network throughput _will_ be reduced, and network latency might increase as
On a ipw2100/2200/2950, you have to use iwpriv get_power/set_power to do it.
I use modes 6 (AC, full time slots) and 7 (battery, shortest possible
slots), for example. There are intermediate steps, but I never found a good
use for them as I am either doing heavy network use and need mode 6, or
interactive ssh sessions, for which mode 7 is quite good enough.
I believe newer cards have to use "iw" instead to set their power management
strategy, since they use the softmac layer in the kernel.
