I have a Linksys WRT54G, and I'd like to know
1) how much power is emitted from the antennas when wireless is active and
2) how much power is emitted from the antennas when wireless is disabled (in the router setup)

Can anybody help?

/best regards

The usual power level is about 35-50 milliwatts with a duty cycle that
varies from 0.01 (mostly beacons) to about 0.75 when transfering data
a full speed. It varies slightly depending on 802.11b or 802.11g
mode. Some firmware versions allow the power to be increase up to 250
milliwatts.

Zero. Nothing is transmitted when the wireless is disabled in the
softare configuration. I've verified this with a field strength meter
and spectrum analyzer.
