Expanding the wifi

[Tubbs_]

I have a router connected to a phone jack in one room, but there is another phone jack on the opposite side of the house. Can i connect another router to that phone jack to spread the wifi network? If I can, how?

If it is just a phone outlet, then no. Your router is using your phone line for DSL input. To add another WIFI source, you need an ethernet link. You could use powerline network adapters to provide an ethernet link to another room
