TP-LINK 150 Mbps Wireless N ADSL2+ Modem Router TD-W8951ND.
Got this from Lamington for Rs.1600.It was the cheapest modem as compared to the others, with the same features.I have an MTNL land line and broadband connection at home.
TP-Link works really well with it.It has a unique design with 4 LAN ports and 1 RJ-11 port.The most important thing I liked about this product is the Wi-Fi button given on its back, which gets you on the Internet with just one click.
Also, there are no speed or flickering signal issue with this modem.
