NETGEAR DGFV338 Restoring the Default Configuration and Password, Problems with Date and Time

DGFV338 ProSafe Wireless ADSL Modem VPN Firewall Router Reference Manual

Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many broadband ISPs restrict access by only allowing traffic from the MAC address of your broadband modem, but some ISPs additionally restrict access to the MAC address of a single PC connected to that modem. If this is the case, you must configure your firewall to “clone” or “spoof” the MAC address from the authorized PC. Refer to “Manually Configuring your ADSL Connection” on page 2-6or “Manually Configuring your Ethernet Connection” on page 2-8.

Restoring the Default Configuration and Password

This section explains how to restore the factory default configuration settings, changing the firewall’s administration password to password and the IP address to 192.168.1.1. You can erase the current configuration and restore factory defaults in two ways:

Use the Erase function of the firewall (see “Backup and Restore Settings” on page 6-26).

Use the reset button on the rear panel of the firewall. Use this method for cases when the administration password or IP address is not known.

To restore the factory default configuration settings without knowing the administration password or IP address, you must use the reset button on the rear panel of the firewall.

1.Press and hold the reset button until the Test LED turns on and begins to blink (about 10 seconds).

2.Release the reset button and wait for the firewall to reboot.

Problems with Date and Time

The E-Mail menu in the Content Filtering section displays the current date and time of day. The ProSafe DGFV338 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 firewall 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 firewall, wait at least five minutes and check the date and time again.
