Any standard wireless router should be able to achieve the above. These usually include a four-port Ethernet switch for plugging into if desired as well. Examples of such a unit include the Linksys WRT54G/GS, D-Link DI-624, Netgear WGR614, etc. etc. Many others are also evailable, your local computer shop should stock plenty of options.
They are all set up using the same basic principle. Connect the cable modem to the routers WAN or internet port, and everything else goes into the switch (such as the desktop) or connects via wireless (e.g. laptops). The end result is that the router connects all of your computers together on one local network, and allows them to all share the single internet connection.
They also provide good inherent security through the use of NAT, so effectively 'hides' access to your computers from the internet. You can still set up rules in the router to allow most types of inbound connection if you do require such a feature, say for remote VPN access or publishing a web server from your home conenction. |
