Setting up a Linksys Router For OlympusNet -Qwest DSL

SETTING UP A Linksys ROUTER & CISCO 678 FOR OlympusNet DSL

A router such as the Linksys BEFSR41 is required for multiple computers to share a DSL connection. The Linksys router also provides basic firewall services to help protect the computers on your network from Internet based attacks. The only condition under which you may have no need for a Linksys router is if you are connecting only one computer and file sharing is inactive. If you have one computer with file sharing active, you will need a Linksys router to protect your computer. For basic security and firewall information, we urge you to read Shields Up!! If you have only a single computer and no hubs or ethernet switches, you should at least protect your computer by a software firewall such as ZoneAlarm Pro. OlympusNet provides additional firewall options. Contact our support staff to discuss your firewall needs.

NOTE: Qwest has been recently shipping a Cisco upgrade CD. Do not use this upgrade CD as it has been known to cause severe problems! The Cisco upgrade is not necessary. No software needs to be installed to use the Cisco 678 in bridged mode with OlympusNet DSL. Ignore any instructions in the Qwest manual to use this upgrade CD.

Connecting the Wires

Before beginning you should confirm that your Cisco modem arrived in the correct operating mode. Turn the Cisco modem over and look for a label reading either "PPP" or "Bridged". OlympusNet DSL customers must use Bridged mode. If the label says PPP you must reconfigure the Cisco to bridged mode by following the instructions in Chapter 5 of the Qwest DSL manual.

Turn everything off. Shut down your computer. The Linksys should be unplugged from its power cord and your Cisco DSL modem should also be unplugged from its power cord.
Connect the yellow ethernet cable from the "ENET" port on the back of the Cisco DSL modem to the "WAN" port on the back of the Linksys. The yellow cable that came with the Cisco modem must be used.
Connect your DSL phone line the Cisco modem
Connect your computer (and any others that will sharing your DSL connection) to the Linksys using standard ethernet cables. These may plug into any of the ports labeled 1-4. If you have many computers, you may want to do this with only one computer until you have DSL working. Other computers can be added later.
Turn everything on. Reconnect the power cord to the Cisco DSL modem. Plug the Linksys power adapter into Linksys router. Turn on your computer.

Configure your Computer Network Settings

The Linksys router will automatically assign all of the IP, Gateway and DNS information necessary for the computers on your local network to access the Internet. All of the computers on your network must be configured to get these assignments from the Linksys. See Setting Your Computer to Use DHCP for specific instructions.

Note: This is exactly the opposite of what is required when using a Cisco DSL modem and a single computer without a Linksys router. In that case, your IP address, DNS and default gateway must all be specified in your computer's TCP/IP preferences.

Configuring the Linksys

Open a Web browser. Your browser will probably complain that it couldn't open your normal start page. Don't worry about it. Enter http://192.168.1.1 in your browser's address (location) line just as you would for a normal Web site.
A window asking for a username and password will open. Leave the username blank and enter admin for the password. Click OK.
The Linksys "Setup" screen will appear. Look for the "Wan IP address" section. Click the circle next to "Specify an IP address" and enter the IP address assigned to you by OlympusNet in the spaces provided. Enter the following information:

Subnet Mask:	255.255.255.0
Default Gateway	65.117.225.1
DNS 1:	198.133.237.1
DNS 2:	198.133.237.19

When complete, the setup screen should look like this. Click Apply at the bottom of the screen.
Mac users should skip to the next step. Windows users: click Start | Settings | Control Panel then open Internet Options. Click the Configurations tab at the top of the window. Click "Never dial a connection" then click OK at the bottom of the window. Close the Control Panel.
Restart your computer. You should now be able to access the Internet.

Resetting the Linksys router to factory defaults

It is possible to reset your Linksys router to its factory defaults which can be desirable if you have made a major configuration error and wish to start with clean slate. This will erase all of your current settings including any password you may have set for the Linksys. To do this, insert the end of a paper clip into the hole above the word "Reset" on the front of the Linksys router. Press and hold for several seconds until the orange "Diag" light on the front panel turns on and off. See page 7 of the Linksys manual for details.
