[Techtalk] Wireless Network Problem. HELP!!! (please?)

Hi E.,
	For a future implementation, I have studied the problem of 
wireless and low power radio on computers for a while now.

	Question: What is this signal blocking wall made of,,, 
lead??? layers of steel mesh?? 802.11b "should" travel through most 
building materials.
Guessing you are correct about the blocking wall. A better improved, 
or directional antenna would greatly help get the signal to the 
"other" office. If I read your text correctly, Why do you need a 
second "access point"?
	It seems to me a better/directional antenna would help your 
cause.   Try taking a Pringles can (aluminum coated cardboard 
can)poke a hole in the bottom, slide it over the antenna on the 
access point and point it in the right direction.
	I am going to do a ad-hoc  802.11b network to eliminate the 
need for an "access point device," I have enough routers switches as 
it is. How about an old PC or two to connect the better antenna(s) to 
and act as gateway to/from the other office?
	There are several commercial antennas with or without signal 
repeaters available. Maybe you can "blast" through that wall. The 
antennas provided with most wireless products are of minimum quality. 
Look for 2.4 or 802.11b antennas.
	I do not entirely understand your troubles, but hope this 
will give you some ideas. I will need help setting up wireless on my 
brand new box once it is up and running.
