This summer, I set up a load-balancing router to have 2 ISPs on one home network to improve my internet connection. I found a cheap TP-Link router on Amazon, plugged in my Comcast and T-Mobile modems, and configured the router to keep one ISP per application and based it on bandwidth. I also set up failover if one connection failed. The internet has been flawless with the load balancing and we have a glut of bandwidth for conferencing, 4K streaming, and security cameras.
