Creating wireless network for small school site....

Hello all. I’m the on site computer tech at a small school. The principal has approved a small budget to provide wireless access throughout the entire school. The maximum amount of money I can spend [per] router is $40.00 and the maximum amount of routers I can buy is six. They will be strategically placed throughout the school for maximum coverage. I need the best wireless router I can get for 40 bux that does well with sending signals through thick walls. I realize that this is a stretch, considering the amount I’ll be spending for each router, that’s why I’m asking you all what the best bang for the school’s buck would be. If any of you have experience with using a router that costs 40 bux or less, and that does a good (or at least decent) job punching it’s signal though thick wall areas, your advice would be greatly appreciated…..

Good luck whit that. Your budget is your enemy. You will not get any bang for your buck at that price. Good AP's (not the best just good) go for over $90 each and then you will need to get good ant.s to go with also $90 or so each. I'm doing a large rv park and I've got $1000. in it so for and climbing all I have left to get around is trees. EnGenius EOC-2610 is a good start I'm getting 500' of good to great signal and bandwidth them. You only need one router witch can make your costs come down but you will need to learn alot more about RF high freq than you may want.2.4.gig is a strange animal.
