Hello, I am a student whose in charge of technology related problems/issues at my high school. Our Science Department would like to get a wifi router to use for the teachers laptops for wireless internet. At most there would be around 10 users using the wifi all within a diameter of around 250-300 feet max. Schools internet I'm assuming, (don't know for sure) is fast, must be 2mbps + could be as low as 1mbps. all I know is that it uses fiber optics, cisco router for the Ethernet cables. Each classroom has 20+ Ethernet ports but for ease of use the teachers want wifi. The signal will have to go through walls, how well does the signal of the Airport hold up through walls? And final questions is would you recommend the airport extreme for such a usage as this? Or would you recommend a more "rugged" wifi router? I personally own the Aiport extreme at home and will most likely bring it in to test it out, but wanted others opinions on the matter. Let me know if you need more details. Let's also assume the budget is around 400 bucks USD. Any Help would be greatly appreciated!
