I am currently using a MTNL triband connection on my Windows XP Professional PC without any problems. In the next 2 or 3 days I am going to assemble a new Windows 7 64 bit computer. I would be grateful if the community here could provide some guidance on what all would be required to set up my triband internet under windows 7.The phone line and router would remain the same. Can I do the set up myself [fiddling with technical stuff is not a problem for me] or is it essential to inform mtnl or ask their guy to come over?Thanks a lot.
