Very true. It's not that the new firmware will drive the transmitter
more, it's that the stock firmware limits the power output. It's my
understanding that the Linksys wireless devices are limited to
somewhere around 24 mw; I believe that is 24 mw into the amplifier,
but I am not positive on that. DD-WRT and Tomato Firmware will allow
you to increase the power level to 251 mw, which is the limit of the
transmitter.

Being that Linksys did not design the ritter/wap to operate at that
level, they did not provide adequate cooling for running the device at
these increased power levels, and doing so will more than likely burn
up the CPU. You can add a heat sink to the CPU, one like a video GPU
cooler, and a cooling fan to get around the overheating problem. My
best friend Google found many sites explaining how to do this.
Personally, I would like to see a water-cooled Linksys WRT-54GL :)

Increasing the power output is not the only way to increase range, and
might not be the best option anyway (increasing power can increase
noise). Quite a while ago Phil sent 3 e-mails with links on how to
make high-gain antenna's for wifi devices. I lost those links when my
laptop died, but maybe Phil and/or others might have those links and
repost them. Now that I think about it, I would get more satisfaction
from getter better performance from home brew antenna's than cranking
up the power.
