I play asphalt 8 with the kids quite a bit. I set up a race over local wi-fi, and we race each other. This works fine at home. Is there a way to do this when we are on the road, or someplace where there is no wi-fi? Most of our ipads have cellular connections, but personal hotspot doesn't seem to allow them to see each other. Is my only choice to buy a pocket router? Or is there a way to setup the ipads for an ad hoc network?
