Answer 1

Answer 2

Most new connection problems can be solved by simply shutting down all your appliances - computer modem and router. Restart in this order: Modem (wait a few min.), then router (wait a few min.) then your computer. You will have to go into your setup on your Linksys router to enable wireless connection. (If you have the CD - the easiest way to do this is running the set up on the CD.) Questions? - Is this a new router? Never has been set up before? No password other than the default one?

Answer 3

Important Note: Due to some operational issues it is VERY important that you have the latest firmware on your Linksys router. Please go to the Linksys Download Website and ensure you have the newest firmware.



Configuration of a Linksys router depends on the type of broadband service and other equipment connected. This is a generalized Linksys Router FAQ and some firmware, capabilities, and actual screen shots may vary. This initial setup is all that is needed to configure and connect your Linksys based network for FastAccess. Any additional setup for features like WEP, DHCP IP ranges, port triggering, etc is out of the scope of this FAQ. Other FAQs may be more appropriate and provide more specific information:

•If you are using a BellSouth supplied Westell 2100/2200/6100 modem please reference the FAQ here.

•If you are using a BellSouth supplied Motorola/Netopia 2210 modem please reference the FAQ here.

•If you here IFITL (PCData) service please reference the FAQ here.

•Both the modem and router must be reset to default.

•The BellSouth Installation CD and Connection Manager are not required to use this configuration.

•Since BellSouth assigns static IPs via your username the configurations shown are applicable to both dynamic and single static IP customers.

• You will be using the PPPoE client built into the Linksys router for connectivity/authentication. Please delete any other unused PPP clients like Enternet300, RASPPP, or the native XP client.



Section 1 - Linksys Router Configuration



Step 1

Verify that your NIC card is set to "Obtain IP Address Automatically". Power down the router and any PCs. Connect one of the router's LAN ports to the computer NIC and power up the router and then the computer. Reset the router to default by pressing the reset button for roughly 25 seconds (exact placement of the button differs per model).









Step 2

Important note: The following screen shots are based on a Linksys BEFSR41v.2 router and your screen shots may be different, however the process and configurations are the same. Open a browser session and enter 192.168.1.1 in the address field to access the Linksys Interface. At the Username and Password prompt enter admin (without quotes) in the Password Field.









Step 3

On the Linksys Setup page select PPPoE from the WAN Connection Type pull down. Enter your BellSouth Username followed by "@bellsouth.net". Enter your BellSouth Password. Select Keep Alive and enter 180 seconds Redial Period field. Do not enter anything in the Host Name or Domain Name fields. If your model has the ability to adjust MTU size (not shown below) select Enable or Manual and enter 1492 in the Size field. Click on Apply to save the changes. You may get a "Settings are successful" message, click on Continue (if required).









Section 2 - Physical Connections and Power Up



Step 4

Power everything down and physically connect the modem, the router, and any computer(s).

Step 5

Power up the network equipment in this order:

•

Westell or Motorola Modem (wait for DSL synch)

•Linksys Router

•Computer(s)

•Open a browser session and enter "192.168.1.1" in the address field to access the Linksys Interface. Click on the Status tab from the menu then click on the Connect button to connect to the Internet.

•Go surfing!









Important Additional Information

•The Westell 6100 and Motorola 2210 modems have an "Internet" light that is green whenever there is an active PPPoE session initiated by the Westell. Since you are using the Linksys to establish the PPPoE session the light will stay off. This is normal.

• Do not change the Linksys Operating Mode from Gateway Mode (default setting) to Router Mode, or it will not function correctly.

•The Linksys "Auto" MTU capability does not function correctly on some models/firmware. You must manually enable the MTU and adjust the size to 1492 (or less). If you are experiencing slow/erratic speeds, constant disconnects, or receive a "Can not obtain IP address from the server" or "PPPoE negotiation fail" errors click here.

•You should check your tweak settings to optimize your new network. Reminder: If you change your MTU, make sure that it is set identically on all equipment (PCs and routers) in the network.

Answer 4

Basically, you plug the Modem into one of the "ports" on the router. Sometimes there is one marked for modem input, if not, any port will do.

You should then connect your computer to the router directly with a LAN cable in order to configure it.

Detailed instructions for your router are available at Linksys.com

Answer 5

First, turn off or unplug all of your equipment, both computer and modem.



Take the Ethernet cable that normally runs from the modem to the network card on the back of your computer and unplug it from the computer. On the back of the Linksys router will be a port marked either 'WAN' or 'INTERNET' (on Linksys equipment, this port is usually YELLOW.) Plug the cable you just removed from the back of your computer into that specially marked port on your Linksys router.



Once you have that hooked up, plug the AT&T modem back in and give it about two minutes to power cycle and boot. Once the modem has booted, plug in the router and give it a few minutes to boot.



Once the router has finished booting, connect a second Ethernet cable (one is usually provided in the box when you buy the router) from one of the open switchports on the back of your router to the network card on the back of your computer (the one we just removed the original cable from.) Power up the computer.



Depending on the type of service you have with AT&T, your computer may simply start working right away... or, if your service is using a protocol such as PPPoE you might have to configure the router a bit before you can get Internet access. Consult the instructions that came with the router and the instructions provided with your Internet service in order to match the configuration settings between the two devices. Hopefully, your AT&T account uses simple IP Protocols with no authentication... if that is the case, you should have Internet immediately upon booting your computer. If not, you will have to connect to the Linksys' built-in configuration GUI (usually at IP address 192.168.1.1) and configure the router for your specific AT&T service.



You will also need to use this GUI in order to set up the wireless settings you will need to allow WiFi devices access to your Internet connection.





If your AT&T modem happens to be one of those that connects to your computer via USB instead of Ethernet (these were VERY common several years ago but are found far less frequently now), then you will NOT be able to connect your USB modem to a router. At this point you will have to contact your AT&T office and request an upgrade from the USB modem to an ethernet modem. They may charge you a small, one-time fee for the upgrade... but without the Ethernet output, you just won't be able to use ANY kind of router with your Internet service; there are NO companies that make a USB-based broadband router.





Good luck with the install!
