Hi Margaret,
I don't have much experience setting up wireless networks but I have some
thoughts you may find helpful. I would first evaluate how much any obstacles
(the trees) interfere with a direct line of sight between the two locations
and how to reduce or eliminate them. Would trimming the trees reduce the
interference? Is it feasible to cut the trees? Consider the construction of
the trailer and your son's house. Could the computers in both locations be
moved to a better location? Getting as close as possible to a direct line of
sight between the two points is the objective.
Secondly, focus on the signal strength and range. As has been pointed out by
several responses, most Wi-Fi access points use omnidirectional antennas.
What you want is a more precise antenna that will focus the signal in the
way that a flashlight's reflector concentrates it's illumination. Commercial
antennas of this type tend to be expensive. I have included a list of links
below for more information in general, but the first two focus on building
an antenna, a "do it yourself" way of solving the distance problem. I have
not built one but both articles appear to be thorough, the methods sound,
and may be a possible solution.

Subject: [PCBUILD] WIFI network
Hi,
I am trying to set up a wifi network for my son and his daughters. The
daughters live on the same property, about 1600 feet behind the dad, and we
are trying to get the signal to go to their trailer. There are some
obstructions like trees which may be in the way. With my laptop I could
pick up a great signal about a thousand feet away, half signal 1400 feet and
then no signal when we get to their driveway. We have purchased a 2.4 GHz
range extender 5 dBi omni directional antenna with a 4 foot cable. It is
connected to a Linsys Wirelss G Broadband Wireless Router. We still cannot
receive a signal to their computers, which do have Linksys WMP54GS
wireless-G PCI Adapters with speedbooster in each of the girls computers.
It still won't reach their computers. I was wondering if there is some kind
of a setup that we can put in their trailer that will draw the signal to
their computers. Oh and their desktops are sitting on the floor.
They all have Win XP Pro.
Thanks very much
Margaret
