There are some suggestions for extending the range of wireless networks
at
http://www.ezlan.net/Distance.html Also, you might consider
replacing the D-Link equipment. The Buffalo WHR HP G54, for example,
has a built-in RF amp to increase power
(
http://www.buffalotech.com/files/pro..._DS-101905.pdf)
Buffalo (among others) also sells various high gain antennas, e.g., :
http://www.buffalotech.com/products/...ional-antenna/
Or, for a perhaps less expensive solution, you could buy an older model
Linksys WRT54G or WRT54GS or Buffalo WHR G54S and use one of the
available third party firmwares (e.g., DD-WRT) that enable you to
control the output RF power (and thus increase it considerably beyond
what the stock firmware runs at). See
www.linksysinfo.org for more details.
Bear in mind, however, that increasing xmit power from the router is
only a partial answer: the link is 2 ways, and the laptops in the
remote location will not be high-power.
What probably will give you the best solution is to set up a wireless
bridge using two Linksys routers with DD-WRT firmware or two Buffalo WHR
HP G54 routers, each of which is connected to a suitable directional
high-gain antenna. You would then connect the two laptops, the VoIP
phone, and the other box to the LAN ports of the end of the bridge in
the remote location (don't use wireless here). The stock Buffalo
firmware supports WDS, but (read below) this cuts available bandwidth.
