I initiated a thread in my facebook defend hackers group for seeking a help to resolve my issue:
I was using a ADSL broadband connection from India's largest ISP - BSNL. I was using an ancient modem/router to connect to Internet - Pronet PN-ADSL 101E/U:
As you can see below it has only one RJ45 out. So I was able to connect only one PC at a time. And currently I have two desktops and a laptop. So it was really headache to wait till my dad or brother accessing Internet on other PC.
So I decided to buy a new one. I went for a ADSL-less wireless router, since I wanted to ensure that the new one will work with cable net too...
