i am trying to connect 3 houses with a wireless network. im trying with just 2 first.
house A has an internet connection and a USR8054 b/g router. it also has a 6db omnidirection antenna. House B i can receive a signal (just barely) but am unable to broadcast back since i dont have an antenna there. House B will have 3 wireless computers in it. im wondering what would be the best way to set that up. could i connect the two routers (setting up A as a gateway for B) and let B serve up those 3 computers? B would have a 6Db antenna on it too of course.
the tolopogy is there is about 175 feet between house A and B with a few trees in between...which i can thin out some if need be. house C is about 300 feet from house A with nothing in between.
it looks kinda like this
B--trees--------A-----------------------C

ive done wireless for awhile...but never tried to connect homes like this.

You probably already know this, but higher gain directional wifi antennae are available. Try googling for "wifi high gain antenna".

so what would you recommend as a setup?
a little more detail.
House B has a G5, a Albook, and a homemade PC. i figure the best way would be to install a wireless router in that house since the G5 has horrific reception and the AlBook doesn't (to my knowledge) support external antenna. i could somehow connect the routers from A and B.
i was looking at the USR 5450 as an option for the second router. seems more powerful than the 8054 (which I was considering purchasing a second for the other router).

House C is a bit simpler. it just has 1 PC. House A is actually an office/computer workshop so there won't be any computers there unless I am working on one for someone and need to download updates, etc.

what antenna strenghts would you recommend? anything over 6DB was pretty darn expensive.
also im a bit confused when it comes to wireless. do i need a super powerful antenna on both ends? i thought as long as its in the "cloud" that it can carry the signal back. right now I can receive a signal from House A inside House B but i can not send any data back.

Sorry, I really can't be much help in this regard. My only advice is to wait and see what others here have to say, and to google around and see what you can find by way of tutorials or other people's experience.

For house C, something like a LinkSys WET54G might be what you need.

thanks. im just trying to decide what i should do. i would prefer to not run Ethernet cable between all three. i think wireless would be the way to go...i just dont want to spend anymore money than necessary. i went and got the $50 6DB antenna hoping it would solve my problem, but it didnt.
then i realized its signal is strong enough to reach house B...but they are not strong enough to broadcast back. id have to get a booster for all three computers in house B. thats why i think just installing a router would be best there.
any advice anyone can give me would definitely be appreciated.

This is basically wireless bridging: router A transmits, router B receives and boosts for clients. While I generally do not recommend Apple's AEBSes, this is a PERFECT situation for one, since they do support wireless bridging. You could then look at some of the QuickerTek products for signal amplification. Or look at MacWireless' interesting solutions. Keep in mind that the AEBSes now support POE (power over ethernet) out of the box.

so if i was going with the 2 router method...could i use the USR 8054 and the 5450? could i get by with 2 USR 8054?
which would need to be my main router? id figure the 5450 would need to be in house B since it supports bridging. it could pick up and redistribute the signal that A was giving out. all i should need is another 6DB antenna and and the other router and i should be good to go.
this is the specs on the two routers i have/will have.
those solutions look good, but a bit pricey.
im trying to do this as cheaply as possible.

The thing is, I don't do this, haven't done it and have only read about it. I don't know about which router(s) need to support bridging outside of Apple's AEBSes. In Apple's case, they BOTH need to be an AEBS. Unfortunately, this is the limit of my knowledge on this subject.

You might find more information on this site:

http://www.wi-fiplanet.com

It looks like it has a wealth of information on WiFi. You would probably get more expert advice by posting in their forums which are dedicated to that topic.
