Assigning a static IP address to a wireless computer always allows it to use the same IP address. This is in contrast to having a router assign a dynamic IP address to your computer where the IP address changes every time you connect and reconnect to the WiFi.
Assigning a static IP address on a wireless computer is useful when:
- Setting up public services on your computer (e.g. FTP servers, web servers, etc.)
- The computer is frequently accessed on the network so that the computer can be easily mapped
- Connecting to online servers (e.g. game servers, file servers, etc.)
It is important to take note of the following settings, which can be obtained through the router's local and internet settings:
- The router's IP address or default gateway
- Subnet mask
- DNS servers
- Router's default gateway: 192.168.2.1
- Computer's IP address: 192.168.2.30
