Haven't used a WRT54G in a while...has Linksys ditched fixed antennas for replaceable ones?

From my (now largely disremembered) CWNA course, changing antennas can increase range, might help w/battery life and keep the FCC from knocking at your door to confiscate your equipment if your neighbors complain about interference..

In the meantime, I'm off to try the recommended settings on my SMC router (with replaceable antennas).
