Dear Linux (thus making this post eligible for posting here :)) users.
Here is an interesting problem.
Introduction: Lets just say Person A has an X company's broadband (512kbps) installed and working already. Person B, who lives opposite to person A would like to share that connection and is able to do so already. (by using a 802.11b router/access point, which is used mainly as a switch and an access point only).
The problem: Limited by range. 3 Concrete walls seperate the access point to Person B thus B cannot use the net effectively. unless B stands outside A's door or is always in A's face all the time.
I (oops, person B) can
1) Get a signal booster which is not easily available or is expensive. 2) An antenna (again expensive) and not tested yet.
OR (ideally) would like to utilize my existing peripherals to "bridge" or "repeat" ?
4) Have seen a lot of articles about the pringles antenna or the yagi shotgun but how do i connect it to my built in device?
Equipment: I have 2 Wireless routers/access points (airlink and netgear mr814) and built in wireless 802.11g. All are standard devices meant for home users.
Limitations: 1)Cost (would like to do it on the cheap as much as possible)
thanks! abhi

You basically want to link two points using 802.11b. Oldhat boring stuff to anyone who has used radios. what is the distance?. are you seperated by a road or buildings.
It is quite simple, but a pain as you have to build all the pieces. From the acess point antenna o/p connect a splitter. You will have to make this using a toroid core and trifilliar wound coil. Put simply three pieces of insulated wire bunched together and looped a few times around the core. Search the web for a design, umpteen available This has three connections 1 input 2 outputs. Input goes to the access point. One end of splitter goes to your existing whip antenna (omnidirectional) for access in region around access point. The 2nd o/p connect to external directional antenna (pringle, yagi, patch, spiral or any of the umpteen designs available on the web) with rj175 cable and stick it outside window/door/terrace. Ideally the reciver & transmitter points should be in line of sight, but you can get around a corner by bouncing of a tall building. Your friend should connect his wifi card ant o/p to another piece of rj175 and connect to another directional antenna. Fire up the power, run squid on your 512kbps terminated m/c, align ur antennas and u r rdy ro go. Since the wifi cards have only a few mw of power bouncing will be a problem. Adding a splitter will half the range of the access point and slow it down, less power=more noise=low bw.
Total cost would be about Rs.1200/- most of it is cable and connectors.
