i want to reinstall windows on my computer because i suspect that it's infected. on xp it was pretty easy to establish an internet connection, you simply had to put the cd in and plug in the usb cord. on vista, which i have now, i don't know how to do this. They gave me a "110BX1 adsl2 + router" thing and somebody came and established the connection. but now that i want to reformat,calling someone over is inconvenient, i want to be able to do this myself. i remember that person who installed it, went to "network connections" and typed in some numbers and other things.. don't the airtel people provide any instructions regarding how to get this done? because i'm clueless can anyone help me out? thanks.
