text: help with wireless router pls? hi am just about to set up a wireless router for my mum and am not too sure what i should be doing does the ethernet cable need to be connected to a comp at all times or just when its getting set up pls help i dont have long thanks in advance xxx ethernet cable just needs to be plugged in whilst you are setting up between the router and the computer once all set you should be able to remove the ethernet cable and work without.  do you not have a free helpdesk number for your router - they could talk you through it.  good luck
