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 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. Refer to
“Manually Configuring Your Internet Connection” on page 3-18
.
Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings, changing the
router’s administration password to
password
and the IP address to 192.168.0.1. You can erase the
current configuration and restore factory defaults in two ways:
Use the Erase function of the router (see
“Erasing the Configuration” on page 9-9
).
Use the Default Reset button on the rear panel of the router. 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 Default Reset button on the rear panel of the router.
1.
Press and hold the Default Reset button until the Test LED turns on (about 10 seconds).
2.
Release the Default Reset button and wait for the router 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
FWG114P v2 Wireless Firewall/Print Server 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”.

As you read this document, you may be directed to various RFC documents for further
information. An RFC is a Request For Comment (RFC) published by the Internet Engineering
Task Force (IETF), an open organization that defines the architecture and operation of the Internet.
The RFC documents outline and define the standard protocols and procedures for the Internet. The
documents are listed on the World Wide Web at

Basic Router Concepts
Large amounts of bandwidth can be provided easily and relatively inexpensively in a local area
network (LAN). However, providing high bandwidth between a local network and the Internet can
be very expensive. Because of this expense, Internet access is usually provided by a slower-speed
wide-area network (WAN) link, such as a cable or DSL modem. In order to make the best use of
the slower WAN link, a mechanism must be in place for selecting and transmitting only the data
traffic meant for the Internet. The function of selecting and forwarding this data is performed by a
router.
What is a Router?
A router is a device that forwards traffic between networks based on network layer information in
the data and on routing tables maintained by the router. In these routing tables, a router builds up a
logical picture of the overall network by gathering and exchanging information with other routers
in the network. Using this information, the router chooses the best path for forwarding network
traffic.
Routers vary in performance and scale, number of routing protocols supported, and types of
physical WAN connection they support.
