I use this modem for some years I am satisfied with this product. This wifi modem has an average signal range when compared to other modems. This device is compatable with BSNL, MTNL, Airtel, Tata broadband and Reliance broadband. How ever Set up will take about 30 seconds.
The company give us proper service for any complaints and which is cheap. We can connect 4 systems at a time in this device. So I would recommend D Link DSL-2730 Wireless N 150 ADSL2+ 4 port router to others.
