For my home network I've purchased a networking appliance form-factor computer, which is basically a regular old an i3 with VT-x support in a fanless case and 4 2.5GiB NICs. I've installed my favorite stable Linux distro that gets regular automated security updates in both host and a VM, and I've device-mapped 3 of the NICs into that VM. The remaining NIC remains unattached to anything unless I want to SSH in to the host. I'm running UFW and Shorewall in the VM to perform firewall and routing tasks. If I want to tweak anything I just SSH in to that VM. I have a snapshot of the VM disk in case I mess something up so I can trivially roll back to something that I know works.

I've purchased a couple of cheaper commercial WiFi access points, and I've placed them in my house with channels set up to minimize interference.

Prior to this I've gone through several iterations of network products from the likes of Apple, Google, and ASUS, and they all had issues with performance and reliability. For example infuriating random periods of 3-5 seconds of dropped packets in the middle of Zoom conferences and what not.

Since I've rolled my own I've had zero issues, and I have a higher degree of confidence that it's configured securely and is getting relevant security updates. In short, my home network doesn't have a problem unless some significant chunk of the world that's running the same well-known stable Linux distro also has a problem.
