There are only two hundred fifty-five other possible numbers. Perhaps looking at the gateway would be a wiser decision, given that 192.168.1.1.

If 192.168.1.1 does not work, on 9x operating systems: Go to start, run, type in winipcfg. Go to your network adapter and find the default gateway there.

If 192.168.1.1 does not work, on NT kernel-based operating systems: Go to start, run, and type "cmd". Type "ipconfig /all" at the command prompt and find your network adapter's information. Look at the default gateway there.

This number will only be different from 192.168.1.1 if someone has changed it from 192.168.1.1, or if the computer is not connected to the router.
