Hi I want to wire up 3 computers and 2 or 3 network printers i understand i have to use a router and connect the broadband to the wan etc everything up to the bit where most routers have only 4 ports so what extra do i need to accomodate more computers and or more printers?? Do i need a hub of somekind?? I must stress i am not looking to go wireless here, weve tried that already and had numerous problems.
