I have a question about wireless networking. With 802.11b the max. range is 300feet, or 100 meters. Are there any amplifiers that will extend this? I know I could probably put another access point somewhere in between, but what if I wanted to extend the length to about 200m on an open field outside where I can't setup another access point?

you can build a beter antenna to help, and yes you can buy boosters but they are pretty expensive last i looked. beter to just make your own antenna for the job. some good guides here:

Pringles/coffee can meathod:

2.4ghz Omni directional using coaxail cable, solder and patience:

what ranges would I get with those?

Tin can antenna will depend on what you make, read the "shoot out" page and some of the links on it for rough ideas of performance.

Same for the omni directional, omni directional may have less range in any one direction that a coffee can (im not sure) as it is omni directional not liniear.

The beuty of them both is they are very cheap to do so if you experiment and it doesent work its no big deal. from the sounds of it, what you are after is a pringles can setup.

you can boost your signal to about 1km range i believe using home built bits such as these. you might need other equipment other than just beter antennae but its possible to stretch it to that distance on a budget.

the pringles can method should do your 200m no problem. you will need a cantenna at each end though dont forget.

becareful as to what wireless you go with make sure you get you a good protection,, because they are way to easy to break in to

I made an 802.11b antenna out of a folders coffee can and we measured the gain, it ended up being 6db, not bad for free!

Also check this page here to see what kind of cards have what connectors, so when you make your pigtails, you know what connector to use.

your right thats not to bad of a gain for what you were working with and free now thats the key word there
