so i have uverse internet, and when i had it installed, they accidentally send me 2 router/modems. i called and they told me to just keep both of them. i want to set up the second one in my room since i get bad wifi signal in the basement, and would like to have ethernet access for gaming, as well as better wifi down here. the routers are identical motorola nvg510. How can i do this without messing up my network? thanks!
