I live on a very high hill and I am surrounded by about 6 unsecure wireless networks. Some of these WIFI spots are as close as 1/2 mile from where I live. My laptop will pick up wireless in my complex but they are all secured networks. My quesion is this; Is there a device that I can get to boost my laptop signal so I can access the unsecured networks, I do not have internet at home so I won't need anthing to boost my internet speed from home. Please let me know what I need to do.
