Router suggestion required

[rext99]

Hi,
I want a router for Bsnl connection. I've shortlisted some basic models -

Asus RT-N10+ - ASUS - Networks- ASUS RT-N10 B1 (RT-N10+ B1)
Netgear N-150 WGR614 Router
TP-Link TL-WR740

Will Asus RT-N10 support dsl connections or is it meant only for connections which require a cable to be plugged directly to a computer ?

Plz suggest which one I should buy.

Thank You
