I have just bought the same
router. However, my primary intention is to use it with
ADSL-MTNL, until that connection is activated, I thought I would give the USB port a try.
So, I inserted
Tata Photon+ in to it. In the advance settings there is option to select primary internet connection. I set this to 3G.
In the following settings for 3G, I noticed that only
D-Link 3G modem is available. I entered Tata's settings in username, password and daignum fields. It didnt work! It couldn't establish internet connection.
Upon checking D-Link's site for documentation, I found that it supports only *compatible 3G adapter*. Which is --
D-Link USB modem only!
(
ftp://support.dlink.co.in/pdfs/products/DSL-2750u/DSL-2750u_ds.pdf : page 2 USB section). So, if you have Vodafone 3G activated card running out of Dlink 3G datacard modem, then it could work for you.Firmware available on Dlink site is date sometime in 2011, so, my Router is already up-to-date. :numbness:
