I'm helping a friend upgrade her computer. She also said she was interested in buying a router to both extend her wifi range and allow her and her friends to connect to the internet without having to deal with everyone else's traffic in the home. I need to know how to set something like this up so I can her what to buy.
I'm assuming she has a modem, and I know she has one router on the other side of the house already. She says she has a phone jack, so my question is this:
Can I just have her buy a router and hook it up to the phone jack, or is there something more to dual-router networking?
