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 lon ger 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 sim ilar external antennas are no longer compatible with this model.

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 an d 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
