Indeed, I am an fan of Asus consumer routers. I am also a fan of OpenWRT and pfSense using Mini PCs.
I started to learn more about home networking after upgrading Singtel Fibre plan from 500Mbps to 1Gbps back in Sept 2018, then wasting quite some money on different stuffs until I changed to use Asus RT-AX82U and virtual OpenWRT/pfSense on Mini PC (dual networks) in late 2020 and early 2021. Since then I am using dual networks -- Asus router on one network and then virtual OpenWRT/pfSense router on another network (with an AP).
Learning diferent aspects of Home networking becomes my hobby now. I spent like about S$2000 to play with 2.5G and 10G home networking over the past three years, with some of the stuff just for testing purposes.
I do not know much about programming but I am involved with various open source projects on the testing and technical support side since 2005. So I am familiar with Linux/macOS/Windows and a bit of BSDs. This may offer a bit ofadvantages in learning about home networking. Still I am for sure not an expert in home networking.
