The Linksys WRT54GS broadband router normally serves 3 different functions; it will allow you to share the internet connection that you receive from your ISP with other computers and laptops and phones in your office or offices or in your home.
It gives you the ability to connect printers, DVDs, and other computing accessories and share their data on all these devices.
It performs the very important security function of protecting your computers from hackers and deters invasions.
So the Linksys WRT54GS wireless router is actually 3 devices in one –
It is an access point for your wireless computers and computing accessories, PCs, laptops and printers, etc.
So you can use your internet wherever you are with no wired connection necessary
The second function that it performs is a 4 port full-duplex switch; This is built into your router and you connect via Ethernet cables – this provides a connection for your wired devices. You can connect four PCs directly, or daisy-chain to more hubs and switches and create as big a network as you wish.
The third function the Linksys WRT54GS performs is to protect your information and computer security with a very effective firewall. As a DHCP server for your network your router stops internet attacks and secures your data.
The Linksys router allows all the separate parts of this network share your single internet connection whether it is provided by High speed cable or a DSL connection. This router and its advantages are an obvious need for a small office or a small business with several different printers and computers on a network and the Linksys WRT54GS works brilliantly for this type of set up. But it is also excellent for any home that is sharing a PC and laptops or smart phones or DVD players or other devices that are working on wireless. The router will provide very vital security for your devices when they are receiving the wireless signal.
Linksys WRT54G uses a networking standard wireless-G which gives a speed up to 5 times faster than the commonly used Wireless-B (802.11b) this wireless – B is used as standard in homes, offices, libraries, and public wireless areas like coffee shops. Both wireless types B and G use the same 2.4 Ghz radio band and so Wireless G devices can be used even if your equipment is Wireless B type – they are interchangeable.
This means ultimately that you don't have to upgrade to the much faster Wireless-G equipment immediately but only need to replace your existing Wireless B devices as your need increases but you can use your new Linksys WRT54GS with existing Wireless B devices and know that their security is protected in the meantime.
The firewall function of your Linksys WRT54GS is one of its best features, because without it your information is vulnerable to invasion. Even if you only have one computer and don't need to share your internet connection a router will protect your data and information from being hacked.
Every router behaves as a firewall and Windows operating systems have their own firewall also but much of the software and browsing systems are not fully functional – they are not maintained and kept current and are prone to invasion. Your router protects you consistently.
