Jennifer lives out in the sticks and has no Internet access. Can she use her cellular internet with her computer? Her reception isn't that great for 3G. Leo says that's not going to work. Latency and lag will kill her internet service over 3G. And the bandwidth caps aren't really worth it either, especially if she's gaming. There are some solutions like Satellite - Dish offers 4G speeds for about $30 a month. Wild Blue Excede is another. Latency will be an issue for gaming with this, though.
What about the Wilson extender? Leo says that doesn't work if she's not within range of a good signal.
