Simple router, terrible doc. The graphic confuses, the sequence involves your computer, your cable modem and the new router. You will need two ethernet cables, one supplied with router. It had me confused for awhile. Forty minutes of confusion, but only five minutes of actual configuring. One part of this is the unfamiliarity.
I last set up a wireless router about five years ago. Today i replaced that router which stopped working.
Cost today was 29 dollars and forty minutes and a little head scatching.
A better diagram could easily be drawn.
