Hi,I have availed a BSNL Data One broadband connectivity and have been using it. The ADSL modem has been set up in the study room ( ground floor ) to a desktop PC.I recently built a first floor and have got provision for a telephone line in my room. I also have a laptop now. I would like to have broadband connectivity at both the places, at the ground floor PC and the first floor laptop.What are the necessary things that need to be done? Should I buy a Network router? Should I try to connect the devices through a LAN connection?Please advice as to what would be the most optimal solution that can be done to achieve broadband connectivity at both the devices.Thanks for your time.Regards
