Modern 802.11 chipsets have pretty good sleep modes. Earlier ones do not. Currently, the good ones waste only 5-10mW while asleep, and they tend to operate at 3.3V. (some 1.8V!) Accounting for the conversion loss, that means that a good 802.11 module will be able to run alone on a PBG4 battery for about 7000 hours, which is the equivalent to nearly 300 days.
THe airport extreme is a little worse on power, but even if it's 5 times worse (which is about right), that's still 60 days. You can do much better for yourself by dimming the display.
