wifi-router

Hey Everybody , Well , I just shifted to a new place and was wondering what to do about the setup at home ? Options :- 1. Buy a Wifi-Router and take Modem from BSNL 2. Buy a Wifi-Router + Modem ? Which is the better option ? and I would be needing the names of Routers :P

Hello guys, I am planning to get myself a wifi router for my home. I have a airtel Broadband Connection. I would need it to cover my entire house (approx 3000 sq. ft) Can you please suggest me a good wifi-router ? What are the things I need to keep in mind before getting one ? Thanks...
