Hi all

I'm a complete novice at this wifi lark so please bear with me. This is the
scenario:

I am trying to set up a simple wireless network.

The house in question is 18th Century stone built, but the main office is
in a new build brick annexe. The office is approx. 20' x 15' in plan. In
this office is the main PC (PC1) which is connected to a 3COM ADSL modem
router with hardware firewall, this unit works very well for me at home.

Adjacent to this in another room is the second PC (PC2) which is separated
from the office by a back to back chimney breast OR two outside walls with
windows.

PC2 is fitted with a PCI wireless network card, but I cannot get better
than a 'Low' or 'None' signal reported by XPSP2. My laptop which is fitted
with a 3COM Wireless PCCard reports a 30% 'Fair' signal adjacent to PC2.

What is confusing me is that my laptop will only report a 98-100% signal
within 3" of PC1's router's antennae. Within the same office at the other
end of the room it drops off to 40-50%. The claimed range for this device
(I guess line of sight) is 100 metres (328ft). I can't get 328 inches!!

I've tried changing from 11g to 11b, all the different channels from 1 - 13
without any noticeable difference.

My original plan was to site a 'repeater' approx midway between the two PCs
but I have had to give up on that for the time being as I couldn't get the
repeater to 'talk' to both the PCI wireless network card and the router. I
could get PC2 to find the repeater and report a 100% signal but I then
lost my network connection. :>(

Am I missing something or am I expecting too much?

Hi
Wireless Distance in general.
2.GHz. is the microwave band; it looses energy on Water molecules. It is
susceptible to 2.4GHz noise, and there is a lot of it around (Microwaves,
Cordless Phones, etc.)If you reside in a Dry climate (like Phoenix AZ.) You
get better Wireless performance then being 200' from the Humid Atlantic
Ocean (which is my bad luck concerning this issue).
Indoors - No obstructions (no walls, or Baroque type furniture), it will go
up to 100' -120'
Once walls get in to the equation it is a fast decline.
One or two "flimsy" (I.e. not concrete full of metal) walls will reduce the
distance to 40-70'.
Three walls or more? You never know until you try.
If you are almost there, a good external Antenna can save you.
Outdoors - With Entry Level Equipment as it is out of the box. You can
cover a little more than above 100 'With Direct line of sight. Using High
towers, and very good directional Antennae it can work for few miles.
The above is a quote from: http://www.ezlan.net/Wireless_Hardware.html
All numbers should be considered as a broads examples. Your actual Wireless
Distance depends on the specific makeup of your envioroment.
