Build a safer baseline
A useful home network also needs to be maintainable and secure.
A few documented settings can reduce risk and make future troubleshooting easier.
Change the router administrator password
Use a unique password and keep the management interface away from the public internet.
Use WPA2 or WPA3
Use the strongest mode all of your required devices support, then document compatibility exceptions.
Keep firmware supported and current
Updates can fix security flaws and stability problems; verify the vendor release notes first.
Separate guests and less-trusted devices
Guest or isolated networks can reduce unnecessary access between personal computers and smart devices.
