Some common errors on the software side of your home network are easy to overlook because the internet will still appear to work fine. Using weak router security settings is one of the most disruptive and damaging. Enable WPA3 Personal if your router and devices support it. If older equipment won't connect, WPA2/WPA3 transitional mode allows compatible devices to use WPA3 while others use WPA2 Personal with AES. Don't bother with outdated options like WEP and TKIP.
If you haven't already, change your router's administrator credentials as well as the Wi-Fi password. Each serves a different purpose: the former prevents unauthorized people from administering your network while the latter controls who can join your Wi-Fi. Replace default administrator credentials with a strong password that isn't something weak like your phone number. Always keep the router's firmware up-to-date so you aren't susceptible to known vulnerabilities.
Another mistake is buying a mesh network setup or new router without checking to see how it will work with your existing equipment. Two DHCP servers handing out addresses on the same network create potential conflicts, so you'll need to use bridge mode or access point mode if you're adding another router. Network equipment instructions should walk you through the right configuration.
Keep it simple, document, and add new features gradually. That sounds a bit excessive, but it makes a huge difference if something goes wrong.
