yes, that's true...but:
a) $100 is a lot more than recycling an old desktop machine (free)
b) $100 routers are toys with very limited capabilities and very
limited configurability. if what you want to do matches exactly
what the menu options allow for, then they're OK. if not, then
they're basically useless.
linux gives you a lot of flexibility that a cheap router just can't
provide. IMO & IME, more flexibility than even a top-end commercial
c) i don't know about you, but i wouldn't be inclined to trust the
security of a $100 consumer-grade firewall. i know from personal
experience that some of dlink's cheaper products have gaping security
holes (e.g. the DWL-900AP+ wireless AP has a flaw which allows anyone
to flash upgrade it over the wireless interface)
d) if size and power consumption is an issue, better to spend $200-$250
USD on something like a soekris net4511 board (an SBC with several
ethernet interfaces, mini-PCI, and 2 PCMCIA slots - they make pretty
good routers, and the PCMCIA slots make them almost ideal for
mast-mounted wireless access points) and install linux on it.
ps: yes, i have a dlink DWL-900AP+ mounted in a box (and powered by 12v
AC over the ethernet cable, regulated to DC) on the mast on my roof.
i'm thinking of replacing it with a soekris board. or maybe a standard
desktop pc in the roof plus about 12 metres of LMR-400 cable to the top
of the mast. my main problem with the dlink is that it has no routing
capability, and almost no diagnostic abilities....it's a black box that
doesn't let you find out what is going on. with a linux box i could run
kismet or airsnort or even tcpdump to help diagnose problems. which is
another reason why linux boxes are superior to commercial routers -
linux, like any unix, has available an enormous swag of useful tools.
