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 r ange. 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 ext ernal 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.

WRT54G3G Mobile Broadband router
A variant which has 4 ethernet ports plus a PCMCIA slot for use with a Sprint Nextel "aircard" which supports CDMA 1X and EVDO rev A wireless internet.
WRT54G-TM
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, using the
same telephone and phone number (a special dual-mode phone designed for the service is required). Additiona lly, 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 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 as was once rumored.
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.
Third-party firmware projects
Although listed here under Linksys, many of these will run on other brands of Linux-based devices, such as the Buffalo network-attached storage series. The extent of support for
(and testing on) particular hardware varies from project to project.
