8.1 240 MHz 8 MB 2 MB MDF0 FCC ID: Q87-WRT54GV81. OS is Linux, no need for Vxworkskiller.
8.2 240 MHz 8 MB 2 MB CDFJ FCC ID: Q87-WRT54GV82. Vxworkskiller works.

WRT54GS[edit]

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 (with appropriate third party firmware).
Version CPU speed RAM Flash S/N Prefix Notes
1.0 200 MHz 32 MB 8 MB CGN0
CGN1
Broadcom BCM4712KPB and ADMtek 6996L switch. Added SpeedBooster technology (Broadcom Afterburner technology), claims to boost the throughput of 802.11g by 30% (for maximum boost needs SpeedBooster technology on the other side, but will boost standard 802.11g as well)
1.1 200 MHz 32 MB 8 MB CGN2 Chipset changed to Broadcom to BCM4712LKFB and BCM5325EKQM switch.
2.0 216 MHz 32 MB 8 MB CGN3 10 LED Front Panel (two new ones behind Cisco logo button). Also capable of SecureEasySetup, but use of the logo button and lighting of the new LEDs behind it requires firmware upgrade. Broadcom BCM4712 chip REV1 or REV 2.

WRT54GL[edit]

Linksys released the WRT54GL in 2005 to support third-party firmware based on Linux,

after the original WRT54G line was switched from Linux to VxWorks, starting with version 5.

The WRT54GL is technically a reissue of the version 4 WRT54G.

Version CPU speed RAM Flash S/N Prefix Notes
1.0 200 MHz 16 MB 4 MB CL7A New model line, released after the version 5 WRT54G, which returns to a Linux-based OS as opposed to the VxWorks firmware. SpeedBooster is not enabled in stock firmware, however third-party firmware will enable the feature. The hardware is essentially the same as the WRT54G version 4.0. One alteration is that the internal numbering scheme of the 4-port switch changed in this model, from 1 2 3 4, to 3 2 1 0.
1.1 200 MHz 16 MB 4 MB CL7B CL7C As of May 8, 2008, this version was shipping with firmware revision 4.30.11. This pre-loaded firmware allows the user to upload a 4MB firmware image, whereas the pre-loaded firmware on version 1.0 limited the image to 3MB. Firmware version 4.30.12 is now available for both hardware versions. Fully supported by Tomato, OpenWrt, and DD-WRT.

WRTSL54GS[edit]

WRTSL54GS is similar to the WRT54GS while adding additional firmware features and

a USB 2.0 port (referred to as StorageLink) which can be used for a USB hard disk or flash drive.

Unlike other models, the WRTSL54GS only has one antenna.

Version CPU speed RAM Flash S/N Prefix Notes
1.0 264 MHz 32 MB 8 MB CJK0 Released after the WRT54GS and WRT54GL. Uses Linux-based OS. Includes SpeedBooster support, additional firmware features, and an external USB 2.0 port (StorageLink) for network storage. Uses 8 MB of Intel TE28F640 flash with a Broadcom BCM4704KPB processor and Broadcom BCM5325FKQM Ethernet switch.
1.1 264 MHz 32 MB 8 MB CJK11 Change from BCM4704 rev 8 to BCM4704 rev 9 unconfirmed

WRT54GC[edit]

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 the 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 1MB flash, 4MB RAM and 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.[3]

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

WRT54G3G Mobile Broadband router[edit]

A variant which has 4 ethernet ports, 1x Internet Wired port (For DSL/Cable connections)

plus a PCMCIA slot for use with a Cellular Based PC Card "aircard".
Model Description Alternative Firmware
WRT54G3G-ST A Sprint Wireless (USA) unit which supports CDMA 1X and EVDO rev 0,A wireless Internet. Fully Supported:

Partial Support

WRT54G3G-AT AT&T (USA) version of the router which supports GPRS and HSDPA (UMTS Maybe?) Partial Support

Partial Support

WRT54G3G-EU European Union version supporting UMTS Fully Supported

Partial Support

Other Cellular Providers

To use this router with other Cellular providers, you MUST use an Alternative Firmware provider. The Stock Firmware does not support Cellular Providers even though you do have the exact supported aircard. eg: Telus Mobility (CANADA) uses the Sierra Wireless Aircard 595 which is supported by this router but because it is from Telus Mobility and not from Sprint (USA), it will never load the card into the router to make it operational.

WRT54G-TM[edit]

The WRT54G-TM (TM stands for T-Mobile) is also called the T-Mobile "Hotspot@Home" service. It allows calls to be made via T-Mobile's GSM network or via WiFi (UMA - Unlicensed Mobile Access), using the same telephone and phone number (a special dual-mode phone designed for the service is required i.e. Blackberry Pearl 8120). Additionally, once a call is in progress, one may transition from WiFi to GSM (and vice versa) 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 like WRT54GL however has 32 ram and 8 Meg flash, with five RJ-45 ports (four LAN plus "internet"). There are no RJ-11 telephone ports nor SIM slots on the v1 model. Upgrading to third party firmware via JTAG method, upgrade CFE to WRT54GL 1.1, allows flash upgrade as the stock WRT54G-TM CFE prevents third party firmware upgrades.
