A:Answeri DON'T KNOW IT DIDN'T WORK FOR ME. I WAS TRYING TO CONNECT WIRELESS TO MY COMPUTER DEST TOP TO HAVE WIRELESS PRINTER.
MAYBE I DON'T KNOW HOW TO USED IT.
A:AnswerThe laptop you described already has a built in wifi adapter, with support for the same speeds as this. It sounds like what you are looking for is a USB Cellular Modem. These allow you to use a sim card to use LTE networks in your area, just like your phone. You will have to pay the higher data use rates in order to use these though.
A:AnswerYes and no. Yes, if are using this for a computer at home and only connect to your home internet. However, if you use this for connection to public WiFi then you do not need to pay for your own provider.
A:AnswerI am not sure. On my desktop pc without Wi-Fi ability, I just plugged it into a USB port and I could connect to my Wi-Fi network with a very strong signal.
