I have been using Dlink 2730 U since 2015. It is very good product from Dlink just like its bigger brother Dlink 2750U( that I had purchased in 2016).
The modem has all sort of things that I wanted. The most valuable feature I liked was its capacity to work on the poorest connection. It manages to work on SNR margin under 10 and with attenuation greater than 40 where other brand modem failed. Moreover even though I am using ADSL line but the modem is future ready with support to ADSL2. Since my purchase no problem have been faced by me. The interface is pretty neat and simple.
