Even though routers should handle the IPs you are assigned, sometimes you need to configure your machine with a manual IP to test some things.

"Can't save IP settings. Check one or more settings and try again."
Do you keep getting this error message on Windows 10 when you try to change your IP settings to manual? Despite knowing how to do it for years on several other versions of Windows? It even works fine if you use the old Network Connections menu. So why are you getting this error? It's because they ask for "Subnet prefix length" instead of the usual "Subnet Mask".
The usual 255.255.255.0 subnets is 24 bits of subnet prefix length. Use that instead.

On Windows 11 they reverted to asking for Subnet Mask again. Perfect to make sure everyone that got used to it on Windows 10 will get confused again! ;)

The most common home network configuration:
Home network routers typically have IP 192.168.0.1 and you can configure the manual IP of your connecting machine by choosing an IP in that range (for example 192.168.0.15) with subnet mask 255.255.255.0 gateway 192.168.0.1 and primary DNS also 192.168.0.1

Reminder that when in doubt you should always let Automatic DHCP IP addressing do it's job for you, when doing manual IP configurations it's more likely to run into IP conflicts. If you desperately want to always get the same IP, i recommend that you log into your router and configure it to reserve you an IP based on your mac address.
