Default Dual RJ45 Lan ports?

Why do motherboards have dual lan ports?

There's a lot of possibilities, for example:
- Connect it to multiple networks/computers
- Connect another computer to it and have them share a connection
- Create a hardware firewall out of the PC by connecting the modem in one port and a router in another port

O ok so would it be possible for me to have it connected via wireless, and then plug in like a laptop using the wired connection?

I assume you mean that if the laptop doesn't have wireless, you can then use the wireless computer's internet, if so, then the answer is yes.

Connecting to two networks is the primary. For example almost everywhere I go, theirs at least two seperate networks. Also sometimes you may want to use multiple IP addresses on the same network, for example a recent fileserver joined the domain under the IP address 10.145.32.14. However it's replacing the fileserver 10.145.32.12, but must still use it's 10.145.32.14 address. Adding a second network card with 10.145.32.12 will redirect all traffic from the old server to the new server.
