How to use a different router than at&t's router/modem?
So I decided to get a new router: the Netgear R6100. Currently, I want to change the router/modem I have from At&t: 2wire 3800HGV-B. My problem is that I don't know how to change the 2wire to my netgear without issues occuring. In short, how can i use a different router than what At&t gave me? If you can help me, that would be great! (I got the new router to have more speed and more wireless range. Also, I need to have uPnP support for a game.)
