Reference Manual for the Model DG814 DSL Modem Internet Gateway
7-8 Troubleshooting
— Check that your PC has the IP address of your router listed as the default gateway. If the IP
configuration of your PC is assigned by DHCP, this information will not be visible in your
PC’s Network Control Panel. Go to the Run… window and run winipcfg. Verify that the
IP address of the router is listed as the default gateway as described in“Verifying TCP/IP
Properties“ on page 3-6.
— Check to see that the network address of your PC (the portion of the IP address specified
by the netmask) is different from the network address of the remote device.
— If your ISP assigned a host name to your PC, enter that host name as the router name in the
Wizard Setup.
Problems with Date and Time
The E-Mail menu in the Content Filtering section displays the current date and time of day. The
Model DG814 gateway uses the Network Time Protocol (NTP) to obtain the current time from one
of several Network Time Servers on the Internet. Each entry in the log is stamped with the date
and time of day. Problems with the date and time function can include:
• Date shown is January 1, 2000
Cause: The router has not yet successfully reached a Network Time Server. Check that your
Internet access settings are configured correctly. If you have just completed configuring the
router, wait at least five minutes and check the date and time again.
• Time is off by one hour
Cause: The router does not automatically sense Daylight Savings Time. In the E-Mail menu,
check or uncheck the box marked “Adjust for Daylight Savings Time”.
