Hi
I've recently purchased a D-Link DWL-700AP and two DWL-122 USB wireless
adaptors for creating a 802.11b wireless network setup. I have deployed
the access point in the middle of the house and have tested the range of
the signal from a laptop.
Unfortunately the device does not extend any further than a few meters in
any direction. On one side of the house, it makes about 10m to the
end of the house and fails to cover the areas furthest away upstairs. On
the other side, there is a fairly thick wall in the way, and signal drops
off at about 5m. I have tested both USB adaptors in ad-hoc mode to see if
the AP may be faulty, but performance does not improve at all. Given that
this signal is not adequate for the task at hand, I will need to purchase
an aerial to improve the range.
I am naturally hesitant to risk buying any more equipment for fearing of
throwing good money after bad. I estimate I need to generate three times
the range horizontally, and cover the remainder of the upper level. I am
using the standard 2.5db gain antenna provided with the access point
currently. The following points are relevant.
* I don't think a directional antenna is the best way to go (as far as
I'm aware), I need to extend the range in both directions horizontal, and
up vertically. Unless I put a directional antenna at one end of my house
and direct it across the entire house (which seems to defeat the point of
the technique), it doesn't seem feasible. However I don't know much about
these things.
* I'm aware that you should have an antenna at both ends for best results,
but there's no way of doing this with the USB without opening it up. I'd
prefer not to do that.
* My calculations suggest that the DWL-50AT won't have the gain I require
to make the system work. I'm not sure what other aerials would be best for
this setup.
I wonder if anybody could give me some advice on this.
Thanks
