I have a Netgear ADSL Wifi router. The router provided to me by TATA Indicom was below par so I decided to use my router. Below are the settings you need to configure your router. Note that you need a router with ADSL modem (like my Netgear DG834G).
Multiplexing method: LLC-Based
DSL Mode: ADSL2+
Encapsulation: PPPoE (Point to Point Protocol over Ethernet)
Login: (e.g. firstname.lastname@example.org, check the receipt given to you for your email ID)
Password: (default is reset123)
That’s it. These the critical values you need. Particularly if you set VPI and VCI values to anything but the ones listed above then you will not be able to connect to the net.
PS: If your plan provides static IP address then chances are that you will be using completely different protocol, e.g. maybe MER (MAC Encapsulated Routing) instead of PPPoE. In that case the above giude is not useful for you.
