I have had basically no issues with my setup: Edgerouter 4 (overkill, had a lower end Edgerouter earlier with no issues except the power adapter died, other hardware was fine). Some pretty basic unifi AP. As well as some cheap dumb gigabit switches. Can basically fire and forget them. Relatively easy to do most things I need on it. Never needed a reboot outside of upgrades. No stability issues, unlike basically all other home grade all in one stuff I have experienced in the past.

I find DrayTek devices to work quite well.

I can kind of recommend Firewalla. They run all open source software under the hood, but their UI is their own. I'm not super impressed with some of the decisions they've made, but it works and has almost every feature a firewall/router device needs.

Things I like

• VPN client support with selective VPN routing. Beats having to manually maintain a routing table for a VPN interface.

• SSH access with sudo to root

• comes with an Ad blocker, but can run pihole in a docker container. I find the onboard ad blocker paired with NextDNS via TLS is good enough.

Things I don't like:

• UI is a phone app. WebUI is neutered. You will require all three (SSH included) to set up any advanced configs

• SSH access is a pain to use.

• Firewall rule creation is kind of a nightmare. I can see what they were going for, but they missed.

• You can't easily configure the onboard IDS or Adblocker. You can dive into the filesystem if you want, but I don't wanna.
