Hello - I purchased a lap top recently and I am in search of what I would term a "WiFi Signal Booster" but when I google that topic, it doesn't seem to be what I have seen and am looking for. I work in a position where I see a lot of traveling sales rep types, and many of them have a device that looks like an antenna. I presume the device would work something like this... Plug antenna looking device into a USB port and boost the signal receiving ability of a WiFi enabled computer. In other words, I have a lap top that I want to use in a low signal area so I need better reception. Anybody know where I can find something like that?
