Linksys Router Setup

Overview: This document will discuss the proper installation of the Linksys BEFSR11 DSL/CABLE Router.

Before using your Linksys BEFSR11 DSL/CABLE Router, let's go over some Physical features of your router.

On the Back (Left to Right):

Reset: This button will reset the router to its original configuration.
WAN Port: The WAN (Wide Area Network) Port is where you will connect your DSL or Cable Modem.
LAN Port: The LAN (Locale Area Network) Port is where you will connect your Cisco 2900 series 24 Port 10/100 Switch.
Crossover Switch: This will change the LAN port into an uplink port, allowing you to connect a single system to the router.
Power: This port is where you will plug the AC Power adapter to the router. The adapter should have been supplied with the router.

On the Front:

LAN:

Link/Act Light: Normally Green, this light will tell you there is a link between the LAN Port on the router and the device it is attached to. Also if this light is blinking, the LAN Port is actively communicating with the device attached to it.
Full/Col: Normally Green, if this light is on solid then a successful full duplex connection has been made. If the light is blinking, data packet collisions have been detected on the network.
10/100: This light can be Green or Orange. If the light is green, this means a 10Mb connection has been mad. If the light is orange a 100Mb connection has been made.

WAN:

Link: Normally Green, this light will tell you there is a link between the LAN Port on the router and the DSL/Cable Modem.
ACT: Normally Green, this light will blink when the router is sending and receiving data over your DSL/Cable connection.
Diag: This light will light RED when the router is powering on. If this light is on for an extended amount of time, this means there is something wrong and you should consult the manual for more information.
Power: This light should always be Green when the router is plugged into it.

Getting Started:

Initial Physical Connections:

To start you should plug the router into a 120V outlet with the Power adapter provided.
You will now need to connect your Linksys Router to a computer with a network card. Plug a CAT5 Ethernet Cable into the LAN port on your Linksys Router and plug the other end into the network port on your Computer.
You should see the link light on your Network Card light up. If it does not light up, switch the crossover switch on the router from || to X.

Configuring your Router:

Now you are ready to configure your router. This will provide step-by-step instructions for basic configuration. If by following these instructions, you are unable to make your network work call Trilogy Networks Support at 1.605.232.0900.

You will need to make sure your computer is set to use a dynamically assigned IP address. To do this use the following instructions:

Right Click on "My Network Places"
Click on "Properties", this will bring you to a "Network" screen.
Highlight TCP/IP for your Network adapter, which could be:

TCP/IP > SMC EZ Card 10/100 (SMC1211TX)
TCP/IP > Linksys LNE100TX Fast Ethernet Adapter (LNE100TX v4)
TCP/IP > 3COM

Click on "Properties", you will see a "TCP/IP Properties Page"
Select "Obtain an IP address automatically."
Click "OK" to accept the changes.
Click "OK" again at the "Network" Screen.
If something was actually changed, the system will update the systems configuration and ask to restart the computer. If it does ask, select "Yes" to restart the system.

Now bring up Internet Explorer and type HTTP://192.168.1.1, this will bring you to a "Network Password Screen".
Just type "admin" in the password box and click "OK" to continue. (Reconfiguration may require user name "admin" and password "ihtdta".)
A Linksys Setup page will appear.
In the Setup tab configure the following items.

LAN IP Address:

Device IP Address: 10.10.1.1
Subnet Mask: 255.255.255.0

WAN IP Address:

"Default" Obtain an IP address Automatically

Use this if your provider is using DHCP to provide their service.

Otherwise you will select "Specify an IP Address"

Here you will specify an IP Address, Subnet Mask, Default Gateway and DNS Addresses (usually two)
The ISP would have provided this information.

Some ADSL ISP's require a user name and password. This is setup through PPPoE. If this is required put your User Name and Password in their respective fields.

The username and password would either chosen by you or assigned by the ISP.

In the DHCP tab configure the following items.

DHCP Server: "Enabled" (unless directed otherwise)
Starting IP Address: 10.10.1.21

You should leave a few IP's free at the beginning of your IP scope, for devices such as switches and printers.

Number of DHCP Users: 100

Usually 100-200 will be plenty for 30 or less systems.

In the Password tab configuration is optional, but for the initial configuration you may wish to make your router a little more secure by changing your password.

Router Password:

Enter New Password:
Re-enter to confirm:

You should now save your changes. Click Save at the bottom of the screen and close out of Internet Explorer.

To make sure the changes take affect, reboot the router by unplugging the power cable from the Router and plugging it back in.

Completing your Physical Connections:

If a CISCO 1605R device is connected to your network share device (switch), please disconnect it now.
You will now need to connect your Linksys Router to your Broadband connection.

Take a CAT5 Ethernet cable and plug one end to your DSL/Cable Modem and plug the other end into the WAN port on the Linksys Router.

To complete the physical installation, you will need a second CAT5 Ethernet Cable.

Plug it into the LAN port on your Linksys Router and plug the other end into a network share device (Cisco 2900 series switch).

You are now ready to browse the Internet. If you are encountering issues please try the some Troubleshooting steps before calling Trilogy Networks (1.605.232.0900).

Troubleshooting:

If some systems are working but some or one is not and your network is not set on static IP addresses, then check to see that all the non-working systems are setup with the following network configuration. Otherwise contact your Network Administrator or Trilogy Networks.

You will need to make sure your computer is set to use a dynamically assigned IP address. To do this use the following instructions:

Right Click on "My Network Places"
Click on "Properties", this will bring you to a "Network" screen.
Highlight TCP/IP for your Network adapter, which could be:

TCP/IP > SMC EZ Card 10/100 (SMC1211TX)
TCP/IP > Linksys
TCP/IP > 3COM

Click on "Properties", you will see a "TCP/IP Properties Page"
Select "Obtain an IP address automatically."
Click "OK" to accept the changes.
Click "OK" again at the "Network" Screen.
If something was actually changed, the system will update the systems configuration and ask to restart the computer. If it does ask, select "Yes" to restart the system.

If all the systems are unable to connect to the Internet, then double check to make sure you didn't miss a configuration step. You may also try to reset the router and re-do the entire configuration.
