Wifi adapter is hungry beast and I'm not surprised it drains
the battery. Since I have no wireless device, I could speculate
on the topic. Recalling from previous posts, it checks from
time to time if it could update news or whatever. Knowing
pcmcia adapter on my laptop, how it heats and imagining
power saving modes for embedded device, I think the bug
mentioned is the culprit. Some operating systems do allow
not to power adapters not in use, but it is tricky at heart.
I'd wait for upgrade and implement it asap.
