Hi, I was wondering if anyone had any suggestions for a directional antenna for the WRT-54G v8. Perferably something that I can buy locally at Radio Shack or Best Buy but it doesn't have to be. Also, I was wondering if this type of antenna will actually increases performance? I'm trying to get a wireless signal to travel from my house to my parents house about 500 ft away or so. I can get a good enough signal outside of the house to get online, but inside I cannot connect unless I open the window. Will a directional antenna help, or is this type of thing not possible. Thanks.
