coax was $5,000 a mile, here, 5-6 mile run (i forget), and they said "there's no guarantee it does anything except TV" - that is, no internet.
fiber loop from cogent or centurylink was $15,000. even though they have a loop a half mile up the road. Dark fiber is probably cheaper, but i cannot remember the pricing to run my own fiber via some legit company. i had DSL (6mbit), switched to my own CPE with cellular wireless, then their CPE after they stopped selling the SIM plan i was using, then starlink after they stopped selling their fixed wireless for some newer one that isn't supported anywhere but metro areas.
There's a tree interfering with satellites at my location, and it's still 20x faster and better than anything before; except my own CPE solution, starlink is only 2x as good as that.
