A lot depends on who you have for options. If you have cable service for television, they will be your best bet for internet. If there is no cable and you have a land line, there may be DSL service but the distance from a wire center is not that far. You need to be within a mile or 2. Last option is internet thru a satellite dish. I think HughesNet may be your only other option. As for the signal in the house, you provider will recommend their equipment for best performance.. It’s best to place the router as close to the center of the house so there are no dead spots. The more floors and walls the signal has to pass through the weaker it gets. If this get to be an issue there are wi-fi signal boosters you can buy that plug into an outlet and use the wiring in the house to boost the signal.
