N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual If the path is functioning correctly, replies like those shown in the previous section are displayed. If you do not receive replies: • Check that your computer has the IP address of your router listed as the default gateway. If the IP configuration of your computer is assigned by DHCP, this information is not visible in your computer's Network Control Panel. Verify that the IP address of the router is listed as the default gateway as described in the online document you can access from Preparing Your Network in Appendix E. • Check to see that the network address of your computer (the portion of the IP address specified by the subnet mask) 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 computer, 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 computers. Many broadband ISPs restrict access by allowing traffic only from the MAC address of your broadband modem, but some ISPs additionally restrict access to the MAC address of a single computer connected to that modem. If this is the case, you must configure your router to "clone" or "spoof" the MAC address from the authorized computer. Problems with Date and Time Under Security in the main menu, select Schedule to view the current date and time of day. The N300 wireless 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. Cause: The N300 wireless modem router has not yet successfully reached a Network Time Server. Check that your Internet access is configured correctly. If you have just completed configuring the N300 wireless modem router, wait at least 5 minutes, and check the date and time again. • Time is off by one hour. Cause: The N300 wireless modem router does not automatically adjust for daylight savings time. In the Schedule screen, select the Adjust for Daylight Savings Time check box. 144 | Appendix A.
