how to make an outdoor rec park a hot spot

I am in the middle of providing a hot spot to the towns local soccer, football and baseballfields. I have a wrt54G ver 5 with upgraded firmware to a dsl router with bellsouth, and a range extender, ver 2, and the hawking booster with their big antenna and heavy cable. The antenna is in the attic of a one story office, shingle roof. About 100 yards away I put the range extender, in a scoreboard, and am thinking of putting another at the ball field quad building (2nd floor), all line of sight. Without the 2nd range extender, I was getting a signal at the quad, but it was a slow connection, 2 bars and 1 mps. Before I buy the 2nd range extender, I wanted to get a blessing from someone in the know, that I was in the right direction. That what I had was good and what I was going to add was good too.

Any other ways to provide unsecure access to parents who are hanging at the park, and the park rangers want web in the quad so they can keep an eye on weather radar via the web.

Your help would be way cool. Thanks in advance.

You are going to hate the results of the range extenders. You are experiencing what I call the "bounce of death" already. It is working so hard to relay the signal that it is slowing down to a crawl and it will relay EVERYTHING it sees which is bad.

Here's the best way to do this in MHO. I do not know the layout of the place you are putting the gear in but you need directional antennas and hubs to get the distance and solid signals. If you put up a router with a high gain omni antenna to fire the signal out into the fields or quad then pick it up with directional antennas on hubs and tie those to simple routers in the areas where the people will be most likely to congregate you can do great things with little signal over great distances.

So... Place a router with a good external high gain omni where your net connection is at. Then, in the really hot areas of human traffic, put a hub inside of a flat panel antenna like a Rootenna and then attach a basic wireless router (200 Mw is the best) and instead of using the stock antenna put a higher gain omni on it and you will be able to go 1000 ft or better with your hub from the main router and then have a 300' raidus or better with the signal from that hubs router. You can have up to 6-8 hubs running and cover the entire area with a HUGE net of internet services. It sounds difficult I know but it really isn't. The rootenna will house the hub and another router and then you just externalize the omni for the router in a location about 5 feet behind the Rootenna panel to prevent signal mushing and interference. Each "package will cost you about $350 or so but it will be a plug and play set up and will require pretty much no intervention on your part. I can't say that much for a "range extender". Those you will beat repeatedly with some poor kids baseball bat.
