Cxx0 General discussions / C-860 & Ambicom Wifi Card

A few months back I picked up an Ambicom WiFi card for my Zaurus.

I can use AC power but I don't want to kill the battery prematurely. Is there some way to throttle the power consumption?
Thanks for any advice!

I use this card with my 860. My opinion is that the battery lasts pretty well, an hour or more. I guess it's just my expectation -- after using the Ambicom in my SL5500 (20 minutes of surfing).
2 suggestions:
-- Wifi draws a lot of juice from the battery, as you've noticed. I've noticed that if I disconnect from the network, the battery % rises. This must be because the high current draw of wifi drops the battery voltage. Once I disconnect, the milli-amps drop to normal, and the voltage rises. So taking a break now and then will extend your surfing time. If you require continuous surfing, yes, plug the 860 in from time-to-time.
-- You can throttle the power by slowing down the CPU. I'm using Cacko ROM. Depending on your ROM, here's how to reduce power consumption:
tap on the battery icon in the system tray,
tap on the Frequency tab (looks like a red stoplight),
tap on "power saving".
