If this LED is continuously illuminated, the connection made through the corresponding port is successfully running in Full Duplex mode. If the LED is flickering, the connection is experiencing collisions. Infrequent collisions are normal. If this LED is flickering too often, there may be a problem with your connection.
Instant Broadband Series Connecting The Cable/DSL Router to Your Network Overview Dynamic IP Addresses A dynamic IP address is an IP address that is automatically assigned to a client station (computer, printer, etc.) in a TCP/IP network. Dynamic IP addresses are typically assigned by a DHCP server, which can be a computer on the network or another piece of hardware, such as the Router. A dynamic IP address may change every time your computer connects to the network.
Instant Broadband Series 4. Connect the power-supply cable to the Power port on the rear of the Router, then plug the supplied AC power cable into a power outlet. Plug the other end into the back of the power adapter. • The Power LED will illuminate green as soon as the power adapter is connected. • The Diag LED will illuminate red for a few seconds while the Router goes through its internal diagnostic test. The LED will turn off when the self-test is complete. 5. Power on the Cable or DSL modem. 6.
Instant Broadband Series 3. The Cable/DSL Router’s Setup page will appear. EtherFast Cable/DSL Router LAN IP Address These values refer to your internal network settings. Unless you have specific internal needs, there should be no reason to change these values. For the internal LAN, the default values are as follows. • Private IP Address: 192.168.1.1 • Subnet Mask: 255.255.255.
Instant Broadband Series 7. Unless you already have a DHCP server on your internal network, choose Enable from the DHCP Server field. By choosing Enable, you will configure the Router to automatically assign IP addresses to each of your PCs. In the Number of DHCP Users box, enter the number of PCs you plan on networking to the Router, or leave it alone. Don’t forget to change this number if, in the future, you add more PCs to your network. EtherFast Cable/DSL Router 3.

If you set the Restore Factory Default option and click Apply, you will clear all of the Router’s settings.
Instant Broadband Series • WAN These fields display the IP Address, Subnet Mask and Gateway IP of the Router as seen by external users on the Internet. • DNS (Domain Name Server) IP Address This field shows the IP Address of the DNS currently being used. Multiple DNS IP settings are common. The first available DNS entry is used in most cases.
Instant Broadband Series Filters EtherFast Cable/DSL Router Forwarding Filters block specific internal users from accessing the Internet. You can set up a filter through an IP address or a network Port number. To Modify Filter Settings • Enter the IP addresses you wish to filter into the IP address fields. The users who have these IP addresses will not be able to access the Internet. • You can also filter users by entering their network port number.
Instant Broadband Series EtherFast Cable/DSL Router Dynamic Routing Static Routing With Dynamic Routing you can automatically adjust to physical changes in the network's layout. The Router, using the RIP protocol, determines the network packets’ route based on the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing information to other routers on the network.
Instant Broadband Series 2. Enter the following data to create a new static route: EtherFast Cable/DSL Router DMZ Host Destination LAN IP The Destination LAN IP is the Address of the remote network or host to which you want to assign a static route. Enter the IP address of the host for which you wish to create a static route here. If you are building a route to an entire network, be sure that the network portion of the IP address is set to zero. For example, the Router’s standard IP address is 192.168.1.
Instant Broadband Series Quality of Service EtherFast Cable/DSL Routers You can also prioritize up to four ports with the Port-based QoS. Port-based QoS (Quality of Service) settings allow you to prioritize performance on four of the routers ports. The Routers other four ports are automatically assigned Low Priority. Port-Based QoS does not require support from your ISP as the ports prioritized are LAN ports going out to your network.
Instant Broadband Series Troubleshooting Common Problems and Solutions This section provides possible solutions to problems regarding the installation and operation of the Cable/DSL Router. Read the description below to solve your problems. If you can’t find an answer here, check the Linksys website at www.linksys.com. 1. I Can’t connect to the Cable/DSL Router. • Verify that the Cable/DSL Router is properly installed, LAN connections are OK, and it is powered ON.
Instant Broadband Series Frequently Asked Questions What is MIB? MIB (Management Information Base) is a data file that works in tangent with third-party SNMP software in managing your Router. To use MIB files in tangent with third-party SNMP software, follow the instructions that come with the thirty-party SNMP software. MIB data files will be available on the Linksys web site: www.linksys.com. Can I use firmware for other routers with my BEFSR81? No.
Instant Broadband Series EtherFast Cable/DSL Routers Can multiple gamers on the LAN get on one game server and play simultaneously with just one public IP address? It depends on the which network game or what kind of game server you are using. For example, Unreal Tournament supports multi-login with one public IP. What is DMZ? Demilitarized Zone (DMZ) allows one IP Address (computer) to be exposed to the Internet. Some applications require multiple TCP/IP ports to be open.
Instant Broadband Series EtherFast Cable/DSL Router Appendix Step One: Pinging for an IP Address SNMP Functions The first step to determining your ISP’s web and e-mail server address is to ping its IP Address. SNMP (Simple Network Management Protocol) is a widely-used network monitoring and control protocol. Data is passed from a SNMP agent, such as the EtherFast Cable/DSL Router to the workstation console used to oversee the network.
Instant Broadband Series EtherFast Cable/DSL Router Step Two: Pinging for a Web Address Installing the TCP/IP Protocol While the IP address returned above would work as your e-mail server address, it may not be permanent. IP Addresses change all the time. Web addresses, however, usually don’t. Because of this, you’re likely to have less problems by configuring your system with web addresses rather than IP addresses.
Instant Broadband Series 7. After a few seconds you will be brought back to the main Network window. The TCP/IP Protocol should now be listed. 8. Click OK. Windows may ask for original Windows installation files. Supply them as needed (i.e.: D:\win98, D:\win95, c:\windows\options\cabs.) 9. Windows will ask you to restart the PC. Click Yes.
