I myself have trouble setting up my Linksys modem/router for airtel broadband. I used their standard modem for connection and my modem/router in only wifi mode. It was not an efficient one but atleast it worked. Finally i found out how to use your modem/router with airtel broadband.
Please note that the following step are for adsl modem/router not for wifi routers
The following steps will guide you :
1. Reset your Linksys router to factory defaults.
2. Choose Encapsulation type to RFC2516 PPPoE
3. Auto-detect : Disable and VC values 1 and 32 for Airtel.
4. DSL Modulation : G.dmt (This is a must for airtel otherwise it will not work).
5. Give your username and password.
6. Rest everything let it be set to default value, save the settings.
7. Check Status -> DSL Connection Status : Should show connected. Or else click on Connect.
Enjoy Internet Connection
