A:AnswerI have not attempted or used it on a mac but as per the specs, it only supports PC. Without the right mac drivers I don't think you'll be able to use it.
A:AnswerIf you meant the signal or speed boost on your router then NO. This will improve compatibility and possibly speed on the device especially if you have an outdated/old wifi card
A:AnswerAs long as you have WiFi in your house, this should pick up the signal, not sure if this helps but if not, try going into Best Buy or contacting your internet provider, either could help if I could not.
A:AnswerNo, this product is designed to connect you to an existing WiFi network. It will work in internet cafes, or other locations where WiFi is available. If you are going to use it at home, you will need a wireless router to serve as your WiFi hotspot.
