Throughout the whole stack, we are not using any tx power adjusting or power saving for wireless devices. This could help to save energy and it could make wireless networks interfere less with each other. Wireless access points should have the option to have this configured to a certain level, max or automatic which is supposed to reduce tx power as well as possible.
IPFire 2.x has already an option to set the txpower in the web interface of the ap page. This is filled with "auto" which mean "max" but could set down by entering a value in db or mw. Im not sure if the other powersave options are a good idea for AP mode. Many of them slow down the network to not wake the cpu. I have seen ping times of several seconds with activate wlan power save.

I guess in all cases the default should be auto, but an AP always sends beacons with maximum transmit power.
