This is not a Mac specific issue so please move it if you need to but, I want to set up a wireless network between my house and my in laws who are only about 180 feet apart. There is nothing major in between us, a couple pine trees but nothing that would block signal. I have a Linksys WRT54GS router and have checked the signal just outside of his house and it is fine. The problem is, there are no windows on that side of the house and the signal doesn't make it through the walls. There is a window just around the corner on the front side of the house so that may work, but I'm thinking it might be best to put up a small outdoor antenna. Where could I get this and what else will I need? Thanks for your help.
