the 3COM 8750 WAP with Dual Radio configuration is the best unit for the
dollar at around 500 buchs a pop. It has a 300 foot coverage radius and
fully supports WPA
The BEST way to BOOST the signal is to get BIGGER ANTENNAS. So Buy a
D-LINK, Senao, Netgear, or other models where they have DETACHABLE antennas
... menaing the rubber ducky antenna screws out.
Then buy a BIGGER antenna from any ONLINE source (make sure you're careful
getting the correct connector on the wire) and aim them at each other.
You can also buy Boosters and amplifiers - they cost money and the
amplifiers can induce NOISE (bad thing) if not used correctly. The easiest
newbie solution is the D-LINK Booster as it is actually a mated amplifier
that connects in-line with the regular AP/router to boost signal. By
In-Line, I mean the GOZOUTA of the AP/Router is connected directly to the
GOZINTA of the booster and PRESTO you get a few hundred milli-amps more
power for longer range/higher throughput.
