The WRT54G is notable for being the first consumer-level network device that had its firmware source code released to satisfy the obligations of the GNU GPL. This allows programmers to modify the firmware to change or add functionality to the device. Several third-party firmware projects provide the public with enhanced firmware for the WRT54G. See Third party firmware projects. This product has been known to be well suited for small businesses.

The WRT54G is also quite notable for being a piece of networking equipment that even novice home computer users understand and use each day. The WRT54G can be thought of as bridging the gap between high-end commercial networking and the now-booming home networking.

Hardware and revisions

WRT54G

The original WRT54G was first released in 2003. It comes with a 4+1 port network switch (the Internet/WAN port is also in the same internal network switch, but on a different VLAN). The devices have two removable antennas connected through Reverse Polarity TNC connectors. The WRT54GC router is an exception and has an internal antenna with optional external antenna. As a cost-cutting measure, the design of the latest version of the WRT54G no longer has detachable antennas or TNC connectors. Instead, version 8 routers simply route thin wires into antenna 'shells' eliminating the connector. As a result, Linksys HGA7T and similar external antennas are no longer compatible with this model. A network switch is a computer networking device that connects network segments. ... A virtual LAN, commonly known as a VLAN, is a logically segmented network mapped over physical hardware. ...

WRT54GS

The WRT54GS is nearly identical to WRT54G except for additional RAM, flash memory, and SpeedBooster software. Versions 1 to 3 of this router have 8MB of flash memory. Since most third parties' firmware only use up to 4MB flash, a JFFS2 based r/w filesystem can be created and used on the remaining 4MB free flash. This allows for greater flexibility of configurations and scripting, enabling this small router to both load balance multiple ADSL lines (multi homed) or to be run as a hardware layer 2 load balancer[2](with appropriate third party firmware, see EzPlanet Load Balancer). 125 High Speed Mode (125HSM) is Broadcoms proprietary frame-bursting and compression technology to improve 802. ...

WRT54GC

WRT54GC series with 802.11b/g support. This unit has a four port 10/100 switch and one WAN port. The "C" in the router number stands for compact, as the unit measures 4" by 4" by 1" with an internal antenna. The unit can be expanded with addition of HGA7S external antenna to boost range. Hardware Version 1.0 is only option available in the United States since introduction in 2005.


Version 2.0 is shipping in, amongst other countries, the United Kingdom. This unit has a non-detachable external antenna.


The internal hardware is based on a Marvell ARM914 ("Libertas") reference design which is probably identical to the SerComm IP806SM, Xterasys XR-2407G, Abocom ARM914, Hawking HWGR54 Revision M, and the Airlink 101 AR315W. By appropriately changing the value of the firmware byte 0x26, the WRT54GC can be cross-flashed with firmware based on the same reference platform.


There are reports that a sister platform of the WRT54GC (the AR315W) has been hacked to run Linux.[4]


WRTU54G

WRTU54G is the yet unofficially announced Linksys/T-Mobile branded router designed specifically for the T-Mobile Hotspot@Home service (now a reality; see WRT54G-TM below). The router appeared on the FCC's website on August 7, 2007.[5] The entry on the FCC was noticed immediately by technology websites.[6] This router has sparked attention particularly because of it has two phone ports on the back panel, and two SIM slots, allegedly allowing VOIP-like functionality through GSM/UMA network technology and introducing T-Mobile into the VOIP industry.


WRT54G-TM

The T-Mobile "Hotspot@Home" service is now a reality, and the actual model number is WRT54G-TM (TM stands for T-Mobile). Further information on the Hotspot@Home system can be found elsewhere, but briefly, what it does is allow calls to be made via T-Mobile's GSM network or via WiFi, using the same telephone and phone number (a special dual-mode phone designed for the service is required). Additionally, once a call is in progress, one may transition from WiFi to GSM (or the other way 'round) seamlessly, as WiFi signal comes and goes, such as when entering or exiting a home or business. A special router is not needed to use the service, but the T-Mobile branded routers are supposed to enhance the telephone's battery life. This is the only known tweak to the TM version of the firmware. The hardware appears to be identical to the other WRT54G variations, with five RJ-45 ports (four LAN plus "internet"). There are no RJ-11 telephone ports nor SIM slots as was once rumored.

Hardware versions affect firmware compatibility

As of January 2006, most third-party firmware is no longer compatible with version 5 of both the WRT54G and the WRT54GS. The amount of flash memory in the version 5 devices has been reduced to 2 MB, too small for current Linux-based third-party firmware. (See table above for information on identifying the version based on the serial number printed on the bottom of the unit, and on the outside of the shrink-wrapped retail box.)


Some users have succeeded in flashing and running a stripped down but fully functional version of DD-WRT called 'micro' on a version 5 WRT54G.[14][15] An easier method not requiring any disassembly of the device has since been devised for flashing v5-v6 to DD-WRT.[16]


To support third-party firmware, Linksys has re-released the WRT54G v4, under the new model name WRT54GL (the 'L' in this name allegedly stands for 'Linux').
