Home Wireless-G Gateway
• If the Gateway is configured correctly, check your Internet connection (DSL/cable modem, etc.) to see if it
is working correctly. You can remove the Gateway to verify a direct connection.
• Manually configure the TCP/IP settings with a DNS address provided by your ISP.
• Make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet
Explorer, click Tools, Internet Options, and then the Connection tab. Make sure that Internet Explorer is
set to Never dial a connection. For Netscape Navigator, click Edit, Preferences, Advanced, and Proxy.
Make sure that Netscape Navigator is set to Direct connection to the Internet.
18.I’m trying to access the Gateway’s Web-based Utility, but I do not see the login screen. Instead, I see
a screen saying, “404 Forbidden.”
If you are using Windows Explorer, perform the following steps until you see the Web-based Utility’s login
screen (Netscape Navigator will require similar steps):
1. Click File. Make sure Work Offline is NOT checked.
2. Press CTRL + F5. This is a hard refresh, which will force Windows Explorer to load new webpages,
not cached ones.
• Click Tools. Click Internet Options. Click the Security tab. Click the Default level button. Make sure the
security level is Medium or lower. Then click the OK button.
Frequently Asked Questions

The Gateway will support up to 253 IP addresses.

Yes, it is a built-in feature that is enabled by default.
Where is the Gateway installed on the network?

IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk,
a communications protocol used on Apple and Macintosh networks, can be used for LAN to LAN connections, but
those protocols cannot connect from the Internet to a LAN.

The Gateway supports 100Mbps over the auto-sensing Fast Ethernet 10/100 switch on the LAN side of the
Gateway.
