Yes. They are quite good and when i had took ADSL connection of BSNL D-Link was most easily available offline. Online shopping was almost non-existent.
My used D-Link modem/routers are:
D-Link 2730u
D-Link 2750u
D-Link DIR-615
I just Googled about them. Now they look different physically from what they were when i purchased. So unsure whether quality remains the same.
