I have been using this modem from past four months and had face no problem till now. It is very compact and great working modem. It is very easy to set up and covers almost entire house even with its single antenna. with wall mounting holes available in the back you can also hang it on the top side of the wall to increase its signal strength.
It comes bundled with One small compact disk, One Lan wire and One Adapter so along with wifi you can connect it with your pc or laptop through Lan wire. And I bought it for almost Rs800 and there is no other Modem better then it in this price range.
