I'm on a Hughes VSAT as we "speak". It's overpriced and incredibly low bandwidth, and a hellish company to deal with for customer service, but it's our only option and we've been using it for over 10 years.
BTW, I'm not using wifi though, I'm using a wire. We find that using the wifi router makes the Hughes bandwidth even slower, and I'm afraid that everyone's random phones and other devices will update their whole software all night and use up the teeny monthly quota. So we hid the wifi router in the cupboard and only use the cable. What we need is
internet, not necessarily
wifi, and it might help to clarify your search. For example, in our town office we've got wifi but the "broadband" internet is usually down, so in town we've usually got wifi but no internet, and that's useless. At our school campus we've got internet but not wifi, and that's useful. Of
course both together would be ideal, but that's not available at this time.
