I have BSNL BB. I have just gone in for Linksys WAG120N (ADSL2+ Modem Router WiFi) over WAG160N, value for money which met all my requirements as a home user.
There are no problems or compatibility issues. However BSNL BB has its own problems (frequently unresolved), like frequent internet connection loss or DSL light flickering. These problems will be there with any brand modem/router. I changed 3 brands (ADSL Modem/Router) and the problem does not go away even with their own supplied CPE (customer premises equipment).
BSNL tech support is generally not uptodate with technology and hence keep recommending specific brands/models, without any real basis.
Coming back to Linksys for home use. WAG120N is much cheaper than WAG160N. Nehru Place price is 3400/- vs over 6000/- for the two models. Unless you want to wirelessly play games between two laptops/desktops within the same house (

), I would recommend WAG120N over WAG160N.
Installation was a breeze. Loaded the CD and followed simple steps and the internet was up and running.
BSNL tech support hesitates in giving you userID/password, something that is rightfully yours and cannot be denied. They even give you incomplete/incorrect information. This is ostentatiously to maintain their re-call value.
