■ If you cannot browse to the Gateway, use the winipcfg utility in

	Windows 95/98/ME to verify that your computer has received the
	correct address information from the Gateway. From the Start menu,
	choose Run and then enter winipcfg. 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 Gateway is
	192.168.1.1 (the address of the Gateway). If these are not correct, use
	the Release and Renew functions to obtain a new IP address from the
	Gateway. Under Windows 2000, use the ipconfig command-line
	utility to perform the same functions.
	■ If you still cannot browse to the Gateway, then use the Discovery
	program on the accompanying CD-ROM as described in Appendix A.

	■ Confirm that the physical connection between the Gateway and the
	cable/DSL modem is OK, and that the link status LEDs on both
	Gateway and modem are illuminated.
	■ Confirm that the connection between the modem and the cable/DSL
	interface is OK.
	■ Ensure that you have entered the correct information into the
	Gateway configuration screens as required by your Internet Service
	Provider. Use the “Internet Settings” screen to verify this.
	■ For DSL users, check that the PPPoE or PPTP user name, password and
	service name are correct, if these are required. Only enter a PPPoE
	service name if your ISP requires one.
	■ For cable users, check whether your ISP requires a fixed MAC
	(Ethernet) address. If so, use the Clone MAC Address feature in the
	Gateway to ensure that the correct MAC address is presented, as
	described on page 60.
	■ For cable users, check whether your ISP requires a fixed Host Name. If
	so, enter the required Host Name in the Internet Settings screen.
	■ Ensure that your computers are not configured to use a Web proxy.
	On Windows computers, this can be found under Control Panel >
	Internet Options > Connections.
