Linksys WRT54G – A successful wireless router saga – Part 1
The WRT54G, WRT54GS, WRT54GL and WRTSL54GS are members of a very popular series of wireless routers produced by the American company Linksys, which in 2008 was bought by another American company, Cisco. The WRT54G was first released in 2003, based on a Linux OS firmware. Since 2005 the WRT54G manufactured devices work on the VxWorks OS. To provide support for Linux-based firmware, Linksys has renamed the original type routers with Linux in WRT54GL from WRT54G.
These routers are suitable for sharing Internet in small networks (for home or small companies).
The fame of the WRT54G model comes from the fact that it is the first consumer-level router that uses a firmware that is based on a free operating system (Linux).
From the WRT54G initial model came out the following:
- WRT54GS – model incorporating SpeedBooster technology which improves wireless performance by up to 35%.
- WRT54GL – After the Linksys WRT54G gave up fitting their equipment with Linux firmware they noted that significant lost in the market share, represented by the enthusiasts who use the G because of the possibility of using it with a modified firmware. As a response, the WRT54GL model was launched, where the “L” letter comes from Linux, as the successor of WRT54G, ver4.
Basically this is a 3 in 1 equipment:
- Wireless Access Point (AP), equipped with two antennas, wireless connectivity 802.11b (11Mbps) and 802.11g (54Mbps) with wireless capable equipments (laptops, desktops, PDAs, etc…)
- A switch with 4 ports full-duplex 10/100Mbps Ethernet 802.3. Each port supports Auto-Crossover (MDI / MDI-X). To expand the number of ports you can use an additional switch.
- Finally, it is of course a router that connects everything together and allows your entire network share a high speed cable or DSL internet connection
The WRT router family does not support Gigabit Ethernet connections.
