Ok, here is an update!
I have not bought the router yet, but will buy in a week or so!
I inquired here, the price starts from about Rs. 1850(Netgear) to 2000 for Linksys and other systems.
I have a few doubts again:
1. Can I limit the speed at which they download from the internet. I don't want a user hogging all bandwidth.
2. I have a laptop(with WLAN card) and an old PC with wired LAN card. Now do I have to buy a WLAN card for old PC too? Or will a straight cable connect router to old PC?
Thank you.
BTW I may go to Lamington Road(most famous electronic market in Mumbai) with Coolg5. Lets see if we get a better deal there!
