Alright, trying to setup a wireless internet at work...I'm pretty much a computer JONG. I would like to send a wireless signal about 500 yards (it's a summer camp, so into several different building, and through a bunch of trees). Currently we have an 802.11b wireless router, but the signal doesn't go far enough. Any experience with either an outdoor antenna, like this http://www.dlink.com/products/?sec=&pid=52 or Pre-N http://catalog.belkin.com/IWCatProdu...duct_Id=184316 Thanks.
