I'm trying to set up my first router and modem, but I'm getting an error that says "WAN ip address and LAN ip address cannot be the same network segment." What's the correct network segment for the LAN side? Also, when I mention my IP as 192.168.0.1, am I referring to the default gateway or my preferred DNS?

To avoid the conflict you're experiencing, the LAN IP needs to be on a different subnet than the WAN. For instance, if your WAN is 192.168.0.x, try using 192.168.1.x for the LAN side. Other options include any address in the 10.x.x.x range.
Avoid static IPs unless necessary—using DHCP is usually the way to go.
Make sure you're choosing a unique address for the LAN side. If your ISP gives you a WAN address, ensure the LAN is set to something like 192.168.1.1 instead of 192.168.0.1.
If you're confused about the terms like subnet, don't worry! A subnet is just a way of segmenting your network, and you want to keep the WAN and LAN distinct.
For your setup, you'll have a WAN IP address provided by your ISP and a LAN IP that you can choose, which usually falls within the 10.x.x.x or 192.168.x.x range. The key is that these two should be different to avoid conflicts.
As for your question about 192.168.0.1, this is typically the LAN side IP and can serve as your default gateway for devices connected to your network.
