You are able to find your gateway address by typing into the command prompt ipconfig. Your gateway address is also your routers IP address.

On Windows systems:

Click Start > Run. Then type: cmd

The 'DOS' box will open, type: ipconfig /all

(Note: there is a SPACE after the word ipconfig) The information displayed will be similar to the below if you have a single address;

C:\Documents and Settings\xxxx>ipconfig /all

Note: Type the word: exit > then hit the Enter key to close the DOS session.

On Mac or Linux/Unix systems:

Launch the Terminal located in /Applications/Utilities/

Type the following command:

ifconfig

You will see most of the same info as the Windows example above. Your IP, subnet mask and gateway will all be clearly marked.
