Ask HN: How to build a village network if the “actual” internet fails (Covid-19)

We're a small village in rural Scotland. Given the present worldwide crisis with COVID-19, should things get worse where backhaul providers are no longer able to provide a reliable service to the "world wide internet", what would be your (affordable) equipment of choice to build out a local village/area network such that within our community we could still maintain communication.

Now I'm well aware that telco services such as 3/4/5G are not going to be practical things to re-implement, I'm thinking about what we can do over wifi(?).
