Common Problems and Solutions

1. I don't hear a dial tone, and the PHONE LED is not lit.
Go through this checklist until your problem is solved:
• Make sure the telephone is plugged into the PHONE port.
• Disconnect and re-connect the RJ-11 telephone cable between the Gateway and telephone.
• Make sure your telephone is set to its tone setting (not pulse).
• Make sure your network has an active Internet connection. Try to access the Internet. If you do not have a
connection, power off your network devices, including the Gateway and cable/DSL modem. Wait
30 seconds, and power on the cable/DSL modem first. Then power on the Gateway and other network
devices.
• Verify your account information and confirm that the phone line is registered with your ITSP.
1. 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):
A. Click File. Make sure Work Offline is NOT checked.
B. Press CTRL + F5. This is a hard refresh, which will force Windows Explorer to load new webpages, not
cached ones.
C. 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.
2. I need to set a static IP address on a PC.
The Gateway, by default, assigns an IP address range of 192.168.1.100 to 192.168.1.150 using the DHCP
server on the Gateway. To set a static IP address, you can only use the ranges 192.168.1.2 to 192.168.1.99
and 192.168.1.151 to 192.168.1.254. Each PC or network device that uses TCP/IP must have a unique address
to identify itself in a network. If the IP address is not unique to a network, Windows will generate an IP conflict
error message. You can assign a static IP address to a PC by performing the following steps:
