I need to set up a network at home so that I can bring a computer downstairs and see what my kids are doing on the computer. I have broadband and use a D-Link Ethernet Broadband Router at present. I run 2 computers from this router but need to run another computer. I really don't want to run cable through the house so thought a Wireless network would be the way to go. Can you recommend the best way to go? My brother-in-law reckons that I can just get a wirelss card for the PC that is connected to the router & network from that! My laptop already has a wireless card in it. Any advice would be greatly appreciated.
