Linksys manual WRT54GS, WRT54GL

Linksys WRT54G series - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/WRT54G#WRT54GL

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 similar external antennas are no longer compatible with this model.

Notes

20 front panel LEDs (including link/activity, collision detection and speed rating indicators for each RJ-45 port). Wireless capability was provided by a Mini PCI card attached to the router motherboard.

Front panel LEDs reduced to eight (one link/activity LED per port, plus one each for power, wireless, DMZ and WAN/Internet connectivity). Wireless chipset is integrated onto motherboard.

Same as 1.1 with a CPU upgrade and greater wireless transmitter integration (fewer transmitter parts). Some of these have 32 MB of RAM but are locked to 16 MB in the firmware (can be unlocked to use all RAM) .

Same physical appearance as 1.1 and 2.0 models. Some of these models have 32 MB of RAM installed but have b een locked to 16 MB by the manufacturer. Some models have two 16 MB MIRA P2V28S40BTP memory chips.

Same physical appearance as 1.1 and 2.0 models. Switching chipset from ADMtek 6996L to Broadcom BCM5325EKQM. Some of these models have 32 MB of RAM installed but have been locked to 16 MB by the manufacturer. Some mo dels have 16 MB Hynix HY5DU28162ET-J memory chips.

Identical to 1.1 and later models, except for the CPU speed and an undocumented switch behind left front pa nel intended for use with a feature called "SecureEasySetup".

The Version 3.1 hardware is essentially the same as the Version 3.0 hardware. Adds "SecureEasySetup" button .

Broadcom BCM5352EKPB Chipset

Broadcom BCM5352EKPB Chipset - Switched to VxWorks OS and reduced Flash Memory and RAM; not compatible with most 3rd party firmware.

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 (with appropriate

third party firmware).[2]

Notes

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)

Chipset changed from ADMtek 6996L to Broadcom BCM5325EKQM.

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.

Radio chip is changed from BCM2050 to BCM2050KML.

Use System-on-Chip: processor, MAC, and switching are handled by Broadcom BCM5352EKBP.

Reduced RAM & Flash

Uses VxWorks OS and reduced Flash Memory; not compatible with most 3rd party firmware.

Broadcom BCM5354KFBG Chipset

WRT54GL

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.
