We don't have cable. We don't have DSL.
All we have is air.
Either satellite air. Or WISP air.
If it's satellite, Comcast or Hughes puts in the equipment.
If it's WISP, we buy & install the equipment ourselves.
The only brand we use is Ubiquiti.
They're great.
Powerful. Cheap. Reliable (except those damn nanos constantly blow up in
the frequent power surges when the winter rains knock trees down over our
power lines).

It's all about the transceivers!
Heh ... we have a standard joke here about "wifi porn" where we post
pictures of our transmitters and access points on towers (since height is
your friend when the first Fresnel zone is your enemy).
We go ten miles between access points pretty easily. More than 15 miles is
difficult but anything less than about 5 miles is a piece of cake. Of
course, it's mountain country, so, that's 5 miles as the crow flies, which
is likely twenty to fifty miles on the ground winding through the road
network.

Plug a spare Ubiquiti nanobridge horn into your laptop (sans the dish).
I've done that. It easily doubles your range, but, the problem is *always*
that the other end doesn't have the same power so, to *really* get range,
you'll need the dish.
I can post a picture of my nano next to my rocket if you want to see the
difference. I have nanos, rockets, and bullets, all of which go miles when
coupled with similar equipment (far less when coupled with a puny Starbucks
router).
Here's a picture of a couple of my nanobridge horns, for example:

I've put magnetic antennas on my auto roof when war driving. :)

You can double or triple your distance by supplementing the horrid antenna
in a laptop. Don't even think of using the far worse than horrid antenna in
a typical iOS or Android device (where I've found iOS to be far worse than
Android in "most" of my ad hoc tests - but I'm sure the iOS guys will
scream hoarse about that informal assessment borne over the years so just
take that as a gentle IMHO advice and not an IMHO that I feel like getting
into a flame war over).

A bullet would work fine too!
You can change the transmit power as needed.

What's amazing to me is that people futz (me included) with puny consumer
routers, when the Ubiquiti equipment is far superior at the same price
points!
For example, we buy these by the dozen:
UniFi wireless access points
