Well, strictly speaking, absolutely no modifications to the router
circuitry or RF sections is legal according to the FCC Part 15
rules-n-regs. About all you can legally do is replace the antenna,
but only with one of either the same type with equal or lesser gain,
or one that the manufacturer has bothered to type certify. So much
for the legal angle.
More interesting is what happens when you crank up the power output. I
haven't run any tests with a WRT54G to see what the spectra looks like
at various power levels. There was a page where someone posted some
really horrible (no graticule) spectrum analyzer photos, but I can't
find it again. As I recall, the spectra stayed fairly reasonable up
to about 80mw (+20dBm). Any more and the spectra looked awful and
possibly/probably/maybe cause problems.
Incidentally, I prefer to solve coverage problems with antennas rather
than boosting the transmit power, but I recognize that it's difficult
to resist the temptation to use maximum power if available.
