Beetel 220BX1 ADSL2+MODEM BSNL Configuration

I was using airtel broadband connection with this beetel 220bx1 adsl2+modem and now i changed my connection to BSNL . The bsnl network came to place and doing all the things on my modem said that your modem is locked by airtel and it will not work . You have to buy new modem from me . I was really disappointed with this reply of him . i have read all the forums and websites , there is same configurations on the websites and forums .

I have done all the thing but modem is not working i think . The yellow light blinking is not blinking and even is reset the modem . It blinks only when i switched off and on it . Please tell me how to do it . I cant buy the new one now and i have to wait for the next month and i want to crack it fast .

when i open the device info .... the default gateway comes blank and Primary DNS Server:192.168.1.1 and Secondary DNS Server:192.168.1.1
Software Version:3.12L.01.A2pB023k.d20k_rc2

Please tell me how to use this modem with BSNL braodband . Please tell me how to crack it

You just need to change the settings by visiting http://192.168.1.1 in any browser to gain access to the modem control panel. After that use the username as admin and Password as password. You might also need to change the VPI/VCI settings in the modem similar to the Dataone's Configuration. I think that it could be 0/35 in case of BSNL Dataone while using the PPPoE settings.
