Configure D-Link DSL-2750U to 3G USB Dongle

[Tajender Singh Virk]

Finally installed the firmware provided by D-Link support guys and it went through as breeze. Now in the list of dongles I see various revisions of D-Link DWM156 and to my surprise Huawei E392 (2G/3G/4G dongle) listed there. I selected D-Link DWM156 A6 (A6 is the firmware revision that I updated my dongle to), keyed in APN settings and the dialup number and hurray, everything started to work.
It is in fault tolerance mode by default i.e. whenever the router looses DSL connectivity, it switches to 3G and as soon as DSL is restored, it disconnects 3G and shifts to DSL line, which is what I want. Do revert for any further queries on this one.

Updated the router software with DSL-2750U_IN_1.10_B038_K8B_0K-IN-00-4459_20130702_test.img and the datacard worked

The ME firmware will enable the use of certain dongles like the Huawei E173x for eg the Idea netsettet E1732. Also ethernet WAN can be used for non-adsl connections. To use it read this https://broadband.forum/topic/61310-how-to-configure-tikona-with-adsl2-router-dlink-dsl-2750u/page-3#entry693953
Tajender, does the latest Indian firmware support Ethernet WAN?

Thanks for this thread which is quite informative on how to use 3G with D-Link DSL-2750U... I have a question. Does this work similarly with Airtel 4G LTE USB dongle? I'm having harrowing time with BSNL connection in Pune. I already have the DSL-2750U setup at my home with all the LAN connectivity and WiFi connectivity with couple of devices. Apart from not requiring to reconfigure entire setup, I don't want to spend more money on buying new hardware to replace the DSL router.
My plan is to subscribe to 4G LTE by Airtel and plug it into the USB slot after following all the above steps of flashing the firmware. Appreciate if anybody has inputs on using 4G with this router. Honestly, I don't know technical differences between 3G and 4G, and their compatibility with the devices consuming broadband stream, but my hunch / logic is that if I can use 4G dongle in place of 3G dongle with my laptop, it should be somehow replaceable and usable with the DSL routers 3G port as well...
Thanks in advance for all the help.

No, I don't think any of the current versions of the 2750u firmware support 4g dongles.
TP-Link TL-MR3220 used to support the older Airtel 4g single mode dongle, but the latest multi mode ones (ZTE MF825A) are still not supported.
Edit: If you get another new modem, the Huawei e392, that's supported by TP-Link, so you'd better ask which modem they'll be providing you with.

Thanks Manoj. I found on the internet that 4G is not supported on 2750u firmware. Actually even support for 3G is pathetic. I contacted D-Link support today and fortunately got the latest firmware upgrade in 'test' dated 2nd Jul 2013 (which others too have mentioned). Flashed the DSL router but I could not find the information to be entered as user name, password, the dial up number and APN for Tata Photon Plus that my office has given me. So now I'm on hunt to know which 3G provider should I select for compatible dongle. Talked with Vodafone 'tech support' and he gave me weird answers ranging from ask DLink guys to 'we don't know the hardware inside the dongle'. Phew. issed-off: . Wasn't even able to connect to airtel guys...

Tajender, could you please share the 3G provider with which things worked successfully for you...?
Thanks in advance...
