ADSL2 + Linksys WRT310N - Setting up a Linksys router for DSL Internet connection

Setting up a Linksys router for DSL Internet connection

This article will guide you on how to properly setup your Linksys router for DSL Internet connection.
Before setting up your Linksys router, make sure that your computer has active Internet connection.  You can do this by connecting your computer to the modem using an Ethernet cable and try browsing any website.  If you cannot access the Internet, contact your Internet Service Provider (ISP).  You can also contact them if you are uncertain about the type of Internet connection you have.
NOTE:  If your Internet service does not involve a modem, you can contact your ISP to verify your connection type and determine what kind of cable is to be used.

NOTE:  Image may vary depending on the type of modem and computer you are using.
Setting up a Linksys router for DSL Internet Connection
There are two ways to do this:

i.      Setting up your Linksys router using Cisco Connect (Setup CD)
ii.     Setting up your Linksys router using the web-based setup page

Setting up your Linksys router using Cisco Connect (Setup CD)

All Linksys devices come with a Setup Wizard for easy installation.  All you need to do is follow the steps provided.  The Setup Wizard/Cisco Connect software will automatically detect the type of Internet connection from your ISP.  If you lost the Setup CD that came with the router, you may download from the Cisco HomeSupport website.

NOTE:  The software assumes that your computer is connected directly to the modem as shown in the image above.

Also, the modem might have the same IP address as the Linksys’ default gateway address.  It is recommended to change the IP address of either the modem or the Linksys router to avoid an IP address conflict.  To learn how to change the IP address of the router, click here.

Setting up your Linksys router using the web-based setup page

The steps provided below will guide you on how to set up your router manually.  It is recommended to do the following steps if the Setup Wizard/ Cisco Connect software did not succeed in setting up the router automatically.

NOTE:  Before doing the following steps, make sure you know the configuration type of the modem.  To know the current configuration type of your modem, contact your ISP.

Step 1:
Connect the computer to one of the Ethernet ports on the router using an Ethernet cable.

NOTE:  Images may vary depending on the type of computer or router you are using.

Step 2:
Plug-in the router’s power adapter to a power source and connect the other end to the power port of the router.

NOTE:  If your router has a power switch, turn it ON.  Observe the power light of your router until it becomes stable.

Step 3:
Access the router’s web-based setup page by opening a web browser such as Internet Explorer or Safari.  On the Address bar, enter your router’s local IP address then press [Enter].  When the login prompt appears, enter your router’s Username and Password.

NOTE:  The default IP address of Linksys routers is 192.168.1.1 while the default password is “admin” and the user name field is left blank.  If you have set a password before but forgot it, you need to reset the device.  For instructions on how to reset a Linksys router, click here.

Step 4:
Set your preferred Internet connection type:

i.     For PPPoE Connection Setting
ii.    For Automatic Configuration – DHCP Setting

For PPPoE Connection Setting

This type of router configuration is ideal for connecting to a modem which is set to Bridged Mode.  A Bridged modem means you need to have a PPPoE dialer setup on a computer or router to activate Internet connectivity.

Step 1:
On the Setup tab, click the drop-down arrow for Internet Connection Type then, select PPPoE.

Step 2:
Enter the PPPoE Username and the Password provided by your ISP.  Select Keep Alive and click on the Save Settings button at the bottom of the page.

NOTE:  The PPPOE password is case sensitive and would not let you save your settings when you have entered the wrong one.  Make sure that you enter the password using the correct letter cases.  For information regarding your PPPoE Username and Password, contact your Internet Service Provider (ISP).

NOTE:  For information regarding your PPPoE Username and Password, contact your Internet Service Provider (ISP).

Step 3:
Click the Status tab.

Step 4:
On the Status tab, click on the Connect button if the Login Status is Disconnected.

NOTE:  If you don’t have Internet IP address and DNS servers under the Status tab you might need to powercycle the router.  Powercycling is done by unplugging the power adapter of the router for 30 seconds and plugging it back in.

For Automatic Configuration – DHCP Setting

This type of router configuration is ideal for connecting to a modem in PPPoE Mode.  This means that the modem may have its router capability activated as well.  This might create a conflict with the router’s routing operation if the IP address of the modem and router are the same.  To solve this issue, you can change the router’s IP address range to eliminate the conflict.

NOTE:  Make sure the modem is not connected to the router while doing the following steps.  Otherwise, you might end up accessing the modem’s web-based setup page.

Step 1:
On the Setup tab, select Automatic Configuration – DHCP for Internet Connection Type.  Then change the value of the 3rd box on the IP Address field.

NOTE:  In this example, the IP address used was 192.168.2.1.

Step 2:
Click Save Settings.

Now that you have configured the settings of the router, you can connect the modem to the Internet port of the router using an Ethernet cable.

You should now have successfully set up your Linksys Router for DSL Internet connection.

Rescuing your DSL password from a Beetel 220BX ADSL2+ Modem

Posted by n00dl3s • Saturday, October 24. 2009 • Category: InSecurity In case it helps anybody...

If you don't know the DSL password which connects your Beetel 220BX to the ISP network (Airtel in India does never provide it to the customers, they'd rather send a guy to enter it by hand...), but the router still functions, you can get the passwords even though you only see ******** in the web-interface. It's really easy:

1. Connect to the router IP with telnet (user: admin, password is the same as for the web-interface)
2. Go to Management (press 9)
3. Go to Settings (press 1)
3. Dump settings (press 3)
4. Look for the line that starts with: ppp_conId1 userName="***********_dsl@airtelbroadband.in" password="cGFzc3dvcmQ=" ....
5. Copy and paste the value of password into a base64 decoder (locally or i.e. you can use an online decoder, such as here: http://www.opinionatedgeek.com/dotnet/tools/Base64Decode/)
6. Congrats, you now have your DSL password which Airtel wouldn't tell you ;)
