Home network with Load Balancing or Failover between 2 ISPs

Hello! This is a guide to setting up a home network with either Load Balancing or Auto-Failover between 2 or more ISPs. The emphasis is on having a relatively low cost way to make a relatively high availability connection from your house to the Internet.

Many of us work from home these days, so having reliable broadand Internet access has gone from nice to have to must have. Also, many of us are "cord-cutters": no Internet connection = no streaming films, TV or music.

ISPs do a great job, but downtime happens. Some ISPs provide backup 4G "dongles", but the author's experience is that these are low speed. And for many households, 4G coverage is not good enough to rely on them as a backup connection.
