Can a laptop go through wifi and a PC through cable?
Question by Lolly: Can a laptop go through wifi and a PC through cable?
Hi – I’m a little confused about routers and how they work. If I plug one into my cable modem does that mean my PC will also use wifi? I really want to route my PC through the cable modem and just use the wifi for my laptop. PC is running Vista and laptop XP. Thanks!

Your router provides a means of sharing your internet connection between several machines, either using ethernet or wireless connections.
As long as the laptop has a wireless adapter then there should be no difficulty in connecting if you follow the instructions in both the router’s manual and the laptop’s wireless adapter’s manual.
It is possible, indeed usual, for both the wired and wireless connections to be used simultaneously.
