I have TL-MR3420 router.

Tried to configure with following 3G modem
Company :DLink
Model :DWM -156
H/W ver: A7
F/W: 7.0.1IN

There are no bin file at India site - ( http://www.tp-link.in/support/3g/)
I tried using the bin provided at global site - ( http://www.tp-link.com/en/support/3g/)
but it did not work. The bin provided for above mentioned modem is for V3.

I tried mailing and calling India tech support line but none of them is receiving my call.
It will be great and helpful for me if I get the bin file for above mentioned modem.

Thanks,
Swapnil
