Run Installation Wizard..

to determine if a modem is also a router:

if it is a router:
1. at the back of the modem you should see 5 ports the first port labeled DSL and another 4 port labeled 1,2,3,4 that is for ETHERNET cable

if it is a modem only:
1. only 3 port that you can see at the back of the westell f90 1 for DSL, 1 for ETHERNET and 1 for power cord.

1. Ensure that your AT&T DSL self-installation kit is complete. At minimum, it should contain a DSL modem, an AC adapter, an Ethernet cable, a telephone cable, several telephone filters and an installation CD.
   
2. Install the telephone filters on each telephone jack that you have a phone plugged into. Install a dual phone adapter on the jack closest to your computer if you have an answering or fax machine, telephone or analog modem in the same room. Then plug your telephone equipment into the filters. Connect the telephone cable that was provided with your installation kit into an unfiltered telephone jack.
   
3. Insert the installation CD into your CD-ROM drive. If the installation program does not start automatically, click Start > Run > and browse to the CD-ROM drive directory to find the installation file.
   
4. Connect the telephone cable that is attached to the unfiltered wall jack to the back of the DSL modem. Connect the Ethernet cable to the back of the modem and to the Ethernet network interface card port on the back of your computer. Connect the AC adapter to the back of the modem and plug it into an electrical outlet. Power the modem on.
   
5. Check the modem lights. There should be at least two lights lit. These will have labels such as "Power" and "Ethernet." However, these labels may differ depending on the model of modem you received in your installation kit.
   
6. Complete the software installation. Enter your chosen username and password when prompted. Check your modem to see if the light labeled "DSL" or "Internet" is lit. Open a web browser window to see if your DSL service has been successfully installed.

No you cant.. But good router I preffer Linksys wrt54G2. Should just be able to plug ethernet from modem to WAN on wrt54g2.

- If you want to connect 2PC's to your Westell, make sure your Westell router has 1 or more Ethernet ports on it for you to connect your 2PC'sto the Internet simultaneously, if hasn't you may need a desktop switch for it.

is this an additional router?

How do I properly set up a D-Link Router with a Westell Modem? (#7125)
This FAQ is for setting up a BellSouth supplied Westell 2100/2200/6100 modem (Models A90-210030-04, B90-220030-04 and B90-610030-06/C90-610030-06, respectively) with a D-Link DSL router. Although actual screen shots vary throughout the DLink line, the instructions below are applicable to all models. Important Note: These procedures and pictures are based on the most recent firmware for the Westell. Other Westell firmware menus and screenshots are slightly different but the bridge options and functions are still available. It is highly recommended that you click here and update your Westell firmware.

This FAQ has 3 Major sections:
Section 1 - Overview
Section 2 - Westell modem configuration
Section 3 - D-Link router configuration information
Section 4 - Connections and power up

Section 1 - Overview
Important Note: Due to some known operational issues it is VERY important that you have the latest firmware on your D-Link router. Please go to the D-Link Support Site for firmware updates.
The best configuration for networking a router with the Westell is to set the Westell to "Bridged Ethernet" mode and allow the router to do the routing and DHCP functions. The Westell is also a router with full DHCP functions and may not function correctly when connected directly to another router. Not changing the modem to Bridged Ethernet will result in double NAT'ing, increased latency, possible IP conflicts, or possibly a network that doesn't work at all.
Before proceeding both the modem and router should be set to default. Despite what the help desk tech tells you, resetting the Westell does not put it into Bridged Mode.
The BellSouth Installation CD and Connection Manager are not required to use this configuration.
Since BellSouth assigns static WAN IPs via your username the configurations shown are applicable to both dynamic and single static IP customers. Select dynamic PPPoE regardless of your setup.
You must connect the Westell directly to the computer's NIC to make the necessary changes before you connect the router, because you will be unable to access the modem interface after you connect the router. The reason is that the modem interface is 192.168.1.254 which is a local IP. By default, most routers do not have the capability to route a local IP out of their WAN port (where your Westell is connected). Additionally, they may be on completely different subnets. After you have made the changes to the Westell you can then connect the router and configure it for use with FastAccess. There are several alternatives around this problem. One method involves extra equipment (second NIC and a hub) and major configuration changes. The second method requires you to utilize the router as a simple switch and use the Westell's PPPoE and DHCP functions. Click here for more information.
If you encounter any problems simply reset the Westell, connect it directly to your NIC, restart your computer, log into the Westell interface, and start over again.
More information about the Westell is available here.

Section 2 - Westell Configuration
Step 1
Verify that your NIC card is set to "Obtain IP Address Automatically". Completely power down the Westell and the computer(s). Power up the modem and press the reset button on the back of the modem. After the modem has fully initialized connect the Westell to the NIC and then power up the computer.

Step 2
Open a browser session and enter 192.168.1.254 in the URL address field to access the Westell interface. If you are unable to access the interface make sure your NIC is set to "Obtain an IP address automatically". This may require you to reboot the computer (or release/renew) to obtain a proper IP.

Step 3
Click on Broadband DSL Line from the top menu. Click on Configure Connection from the right menu. Select "Bridged Ethernet" from the Protocol pull down. Click on Save and restart the connection at the bottom. This will automatically restart the modem and the interface will return after the changes are saved. Note: functions like NAT, DHCP, IP Passthrough, and username and password will be disabled or irrelevant and can not be selected. After the modem has restarted, power down both the computer and the modem then physically disconnect the Westell.

Section 3 - D-Link Router Information
Step 4
After the PC is powered down connect one of the router LAN ports to the computer NIC and power up the router and then the computer.

Step 5
Use the following steps to configure your D-Link DI-604 Router. Important Note: You must use the [email protected] format for your username. If you do not add "@bellsouth.net" after your username you will be unable to connect to the internet.




Section 4 - Connections and Power Up
Step 6
Power everything down and physically connect the Westell, the router, and any computer(s).

Step 7
Power up the network equipment in this order:
•Westell Modem (wait till the Ready light is a steady green)
•D-Link Router
•Computer(s)
Open a browser session and go surfing!

Additional Imformation
•You should check your tweak settings to optimize your new network. Reminder: If you are required to change your MTU, make sure that it is identical on all equipment (PCs and routers) in the network. For more information about changing MTU on a D-Link please click here.
•The 6100 has an "Internet" light that is green whenever there is an active PPPoE session initiated by the Westell. Since you are using the DLink to establish the PPPoE session the light will stay off. This is normal.

To be honest, I have installed several routers of my own and it runs better without the installation CD. Those CD's are controlling and make your life harder. All you need to do is turn off your computer. Then turn off your cable/DSL modem and unplug the power. Take the router, position it where you want, and plug in an ethernet cable going from the Modem to the back of the router in a slot labeled Internet. Then power on the modem and let it run for 1 min. Then power on the router, let run for 1 min. Take a second ethernet cable and plug it into your router labeled "1" and into the computer. Turn on the computer and check to see if you have internet. If you do, then you are good to go.

If you need additional help, contact me with a direct message.

You can only use one or the other.

What you need is another router to plug the Westell one into. I have the same Westell modem and what I did was I plugged it into a wireless modem (since my Wii and Laptop use wireless) but it also has 4 LAN ports in case I need them.

Hi,

Hook up the Cable from the DSL or Cable modem to the Router. Run one cable from the router to your main computer.
Open up Internet explorer and type in 192.168.0.1. or 192.168.1.0 to access the router setup . Run the setup wizard,
