3. For the IP address, type the address you want to use (e.g., 192.168.1.107).
Often, networks don??™t work because Windows and your
router are unable to negotiate the correct addresses automatically.
The first three numbers in each PC??™s IP address (e.g.,
192.168.1.xxx) must exactly match the first three numbers
in the IP address of your router??”usually 192.168.1.1 or
192.168.0.1??”which you can get from your router??™s documentation.
The last number (e.g., 100, 101, 102) must be
different for each PC.
4. For the Subnet mask, type 255.255.255.0.
5. For the Default gateway, type the IP address of your router (usually
192.168.1.1 or 192.168.0.1).
