Thank you for the quick reply. As usual, I'm not very clear. If I add a WiFi extender, how does it connect to my laptop (there is no external antenna port)? Does it simply plug in to a USB port? If so, will the laptop find the external antenna and use it instead of the internal antenna?
The connection to the Wifi extender is, well, wireless. What it does it provides a link between your computer and the wireless router. Your laptop will recognize the signal as though it was just the router itself, only closer.
