I run a Netgear DG814 DSL modem/4-port router which currently provides networking and DSL access to my three PCs. I want to add wireless capability to connect another (potential) PC elsewhere in my home. I know very little about wireless (well, less than that really) so I need a few pointers. Am I right in thinking I need to add a Wireless Access Point device? I guess this connects to one of the ports on the router and then other machines can connect via wireless - is this right? In simple terms I want to expand the current network to include a wireless device or two.
