pl provide firmware for TP-Link MR3040 with ZTE AC8700.

Dont have that, get in touch with TP-LINK support to get alternate firmware for your router - http://www.tp-link.in/support/contact/

Sir, thanks for details. I want to know that after then speed bsnl evdo. thanks for regards.

I don't fully understood your comment but if you meant the speed after firmware upgrade, I would say it works as earlier. To get best EVDO speeds I would suggest you try various antenna angels and locations.

DOes it work perfectly with ZTE AC8700 BSNL EVDO modem..?

DOES IT WORK CONTINOUSLY WITH ZTE AC8700..

Problem with previous router MR3220 was ...It was identifying and connecting modem,,but when i start downloading, after 10-12 minutes of downloading..the router was getting disconnected..
i got refund from snapdeal.com

It's working 24/7 for me without any issue with ZTE AC8700 BSNL EVDO modem, however I guess your issue can be because of poor EVDO signal reception. Does it work as expected when directly connected to your PC ?

Thank you very much, you helped me a lot, using the network presently to post this!
