Configuring Linksys WAG200G (Wireless ADSL Router) with BSNL broadband

Friday, February 6th, 2009

Linksys WAG200G is a wireless ADSL gateway for home networks. This wireless router also boasts of an inbuilt ADSL modem and can directly connect to the telephone line. This tutorial shows how to configure your WAG200G modem with a BSNL dataone broadband connection.

This tutorial is split into two parts. One, to configure the router to connect with a BSNL dataone connection. Two, to configure an ubuntu client to connect with the router through a Netgear wireless USB adapter.

Part One – connecting with BSNL dataone

The first step would be to open a browser window and type “http://192.168.1.1″ to access the web configuration page of the wireless router. The default username and password is admin/admin.

The screenshot below depicts the basic settings that work for BSNL connections.

The encapsulation needs to be set to PPP over Ethernet (PPPoE) and the Qos to unspecified bit rate (UBR). UBR is normally intended for non real-time applications that do not expect a maximum bound on the transfer delay. BSNL also expects a virtual circuit (channel) connection with VPI/VCI values of 0/35. The DSL Modulation can be set to Multimode.

The next step would be to configure the DNS settings. BSNL primary and secondary DNS IP addresses are 61.1.96.69 and 61.1.96.71. The new set of DNS on my connection appears to be DNS1: 218.248.240.181 and DNS2: 218.248.240.180. You can try with any of them and use the one which works.

The following screenshot shows the wireless configurations to enable wireless clients to connect with the router. Please note that the SSID can be an alphanumeric of any value that you prefer to name your home wireless network.

It is important to secure your wireless network and the preferred security mode is WPA-Personal (Wi-Fi Protected Access) standard that was created to overcome several shortcomings of the earlier WEP (wired equivalent privacy) standard. The WPA standard is based on TKIP (Temporal Key Integrity Protocol) algorithm that secures the wireless network with a passphrase. Please enter an alphanumeric that you prefer the TKIP to make use of, in securing the wireless network. This passphrase shall be required for authentication purposes when accessing your home wireless network.

The following four screenshots depict the ADSL connection status after the above the configurations are made. If the configurations are successful, the DSL connection status screenshot shows the DSL status as “connected”. Please note that these setting shall vary with your ISP and the above configurations are recommended only for BSNL ADSL connections.
