•Check 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.

•Check that your cable or DSL modem is connected and functioning.

•If your ISP assigned a host name to your PC, enter that host name as the account name in the Basic Settings screen.

•Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many broadband ISPs restrict access by allowing traffic only from the MAC address of your modem, but some additionally restrict access to the MAC address of a single PC connected to that modem. In this case, configure your modem router to clone or spoof the MAC address from the authorized PC.

Changes Not Saved

If the modem router does not save the changes you make in the modem router interface, check the following:

•When entering configuration settings, always click the Apply button before moving to another screen or tab, or your changes are lost.

•Click the Refresh or Reload button in the Web browser. The changes might have occurred, but the old settings might be in the Web browser’s cache.

Incorrect Date or Time

Select Security > Schedule to display the current date and time. The modem router 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 the following:

•Date shown is January 1, 2000. This means the modem router has not yet successfully reached a network time server. Check that your Internet access is configured correctly. If you have just finished setting up the modem router, wait at least 5 minutes, and check the date and time again.

•Time is off by one hour. This modem has automatic DST adjustment. To use this feature, in the Schedule screen, make sure this check box is checked: Automatically adjust for daylight savings time.
