Hi, Linda, If your laptop is less than 5 yrs. old, it prob. already has wireless "reception" built in and you would not need the "wirelss USB port" assuming you mean a wireless USB reception device........ Cora _________________ Hi Gang, May I answer all the questions here at once as each is connected to the other, to the laptop. 1.start with a basic service of phone co. 2.then add a router, a 5 port is plenty, as it splits the phone signal for multi computer use within that area. each p/c will not have interference of anothers use, 3. the Magic Jack Plus is for wireless use, but is plugged into the router not the laptop, the orginal MJ required a p/c to function and kept the p/c tied up..and on. 4. from the router i will be plugging in a wirelss USB port. this allows me to wander the house with the laptop while in use. Now if this works, it will be a miracle! believe me. ~ Linda ~ Willow Creek,CA.
