We too live in the countryside but Spain. No chance of copper or fibre ever..
Our choice is 4G or 5G ( when available) The 5G will have roughly the same footprint as 4G . At max 20 meg 4 G works for TV streaming until “ rush hour” . Schools in/ out, work finishes, adverts on popular programmes etc etc. Up is 700k so useless for video conferencing.
Spain has a programme to enable everyone to get fast internet. We get HispaSat internet. 100 meg down and 7 meg up for 35 euros a month - Free install. It works great for tv streaming but has a big ping so no good for interactive internet gaming. We are currently waiting for technician to visit to give us a free speed upgrade.
Our install is a 90 cm dish facing South East , cable to a good quality router
Similar technolgy to Starlink. Starlink have offers . Look out for one……..
