CDF0/CDF1 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. |- |WRT54G 1.1 |125 MHz |16 MB |4 MB |CDF2/CDF3 |Front panel LEDs reduced to 8 (1 link/activity LED per port, plus one each for power, wireless, DMZ and WAN/Internet connectivity). Wireless chipset integrated onto motherboard. |- |WRT54G 2.0 |200 MHz |16 MB |4 MB |CDF5 |Same as 1.1 with a CPU upgrade and greater wireless transmitter integration (fewer transmitter parts). |- |WRT54G 2.2 |200 MHz |16 MB |4 MB |CDF7 |Same physical appearance as 1.1 and 2.0 models. Switching chipset from ADMtek 6996L to Broadcom BCM5325EKQM. |- |WRT54G 3.0 |200 MHz |16 MB |4 MB |CDF8 |Identical to 1.1 and later models, except for the CPU speed. Undocumented switch behind left front panel intended for use with a feature called "SecureEasySetup"[1] for setting up wireless security. This button is illuminated with a Cisco logo on it, to the left side of the router. To activate this feature, upgrade the firmware to the latest Linksys one. |- |WRT54G 3.1 |216 MHz |16 MB |4 MB |CDF9 |The Version 3.1 hardware is essentially the same as the Version 3.0 hardware. The SecureEasySetup button has been activated by the original firmware included in this model, even though the switch existed in Version 3.0.

There is new (EU?) firmware version 4.20.8

WRT54GL version CPU speed RAM Flash memory 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 internal OS as opposed to the v5's VxWorks firmware. NOT SpeedBooster enabled in stock state (third party firmwares however, like DD-WRT, will enable the SpeedBooster feature on this model, as it is hardware independent). Essentially the same as the WRT54G version 4.0, but with a new model number.
1.1 200 MHz 16 MB 4 MB CL7B No known major differences from the above mentioned WRT54GL version 1.0.
WRT54GS version CPU speed RAM Flash memory S/N Prefix Notes
1.0 200 MHz 32 MB 8 MB CGN0/CGN1 Added SpeedBooster technology (Broadcom Afterburner technology), boosting the throughput of 802.11g by 30% (needs a wireless card with SpeedBooster technology on the other side to work)
1.1 200 MHz 32 MB 8 MB CGN2 Chipset changed from ADMtek 6996L to Broadcom BCM5325EKQM.
2.0 200 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. Use Hynix RAM.
2.1 200 MHz 32 MB 8 MB CGN4 Add SecureEasySetup. Radio chip is changed from BCM2050 to BCM2050KML.
3.0 200 MHz 32 MB 8 MB CGN5 Use System-on-Chip: processor, MAC, and switching are handled by Broadcom BCM5352EKBP.
4.0 200 MHz 16 MB 4 MB CGN6 Reduced RAM & Flash
5.0 200 MHz 16 MB 2 MB CGN7 As of Jan 2006 - Switched to VxWorks OS and reduced Flash Memory; not compatible with most 3rd party firmware, except possibly DD-WRT micro edition. See here for more information.
5.1 200 MHz 16 MB 2 MB CGN8 Still using VxWorks OS.
