Troubleshooting

LAN Connection Failure

sEnsure the Modem is properly installed, the LAN connections are correct, and the power is on.

sConfirm the computer and Modem are on the same network segment. If unsure, let the computer get the IP address automatically by initiating the DHCP function (see “DHCP Server” in chapter 3), then verify the computer is using an IP address within the default range (192.168.1.64 through 198.168.1.254). If the computer is not using an IP address within the range, it will not connect to the Modem.

sEnsure the Subnet Mask address is set to 255.255.255.0 by clicking Status in the “Main Menu” screen.

Cannot Connect to the Internet

sEnsure the Subnet Mask address is set to 255.255.255.0 by clicking Status in the “Main Menu” screen.

sVerify the Modem’s settings are the same as the computer by clicking Status in the “Main Menu” screen.
