Actually, we use mostly wifi in our marina in Bayfield, WI, but often times the signal at our slip is marginal. Now we're back to wifi amplication or external antennas, none of which we have tried so far have been worth the hassle. (I have yet to try the 5mile unit.) But I guess, we are not cool or hip. Just a neanderthal with one laptop connected to wifi at the dock. I don't envision other devices on the internet, at least on this boat. On Lake Superior cell service is marginal at best unless we are near a larger town like Duluth or Houghton/Hancock, and usually there is no service at all on the open lake.
