Sure, follow the article and you will get things.....working but will also turn you into a SysAdmin.
Homelab is my hobby, CLI aka command line interface is where I spend most of the time playing with my linux containers BUT you do wanna a GUI to manage network stuff.
Do you wanna do this right and once?? And trully open-source meaning, you will never have to pay to use it??
1. OpenWRT: It supports many WiFi6/7 wireless router, it provides you router, wireless, basic firewall, plugins. Set it once and forget. My dumb OpenWRT wireless only access point has been running for years. It used to be my main router, same device.
2. OPNSense: This is like going from an EV to a V12 bi-turbo: It will work out of the box, you change things ONLY if you wanna mess around. Provide your ISP login when installing it and everything works out of the box.
My OPNSense baremetal has dozens of firewall rules and what not but from an every day life pov, I do not touch it other than check for updates and neither should you.
Good luck troubleshooting network problems via CLI only if you have no idea of what is going on and just followed some article online.
