102 CHAPTER 6: TROUBLESHOOTING ■ If you cannot browse to the Router, use the winipcfg utility in Windows XP to verify that your computer has received the correct address information from the Router. From the Start menu, choose Run and then enter cmd. Check that the computer has an IP address of the form 192.168.1.xxx (where xxx is in the range 2-254), the subnet mask is 255.255.255.0, and the default Router is 192.168.1.1 (the address of the Router).
