I sure a lot of you guys are much more knowledgeable about such things than an oldie like me. What do I need to do to make my A3 a Wi-Fi hotspot mainly so that I can use my android tablet inside the car. I know quite a lot about computers in general having supported a network for 25 years but I know very little Wi-Fi hotspots in a car. I do not have any of the Technology packs with my A3. Any help would be much appreciated.
