■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). If these are not correct, use the Release and Renew functions to obtain a new IP address from the Router. Under Windows 2000,XP,and Vista, use the ipconfig/all command-line utility to perform the same functions.

■If you still cannot browse to the Router, then use the Discovery program on the accompanying CD-ROM as described in Appendix A.
