Hardware versions affect firmware compatibility

As of January 2006, most third-party firmware is no longer compatible with version 5 of both the WRT54G and the WRT54GS. The amount of flash memory in the version 5 devices

has been reduced to 2 MB, too small for current Linux-based third-party firmware. (See table above for info rmation on identifying the version based on the serial number printed on

the bottom of the unit, and on the outside of the shrink-wrapped retail box.)

Some users have succeeded in flashing and running a stripped down but fully functional version of DD-WRT ca lled 'micro' on a version 5 WRT54G.

[13][14]

An easier method not

requiring any disassembly of the device has since been devised for flashing v5-v8 to DD-WRT.

[15][16]

To support third-party firmware, Linksys has re-released the WRT54G v4, under the new model name WRT54GL (the 'L' in this name allegedly stands for 'Linux').

CPU

According to OpenWrt,

[17]

the Linksys WRT54G series use several different processors, all of them 32-bit MIPS architecture processors manufactured by Broadcom.

Performance

The WRT54G CPU can be overclocked using a third-party firmware, such as DD-WRT. Overheating may accompany overclocking since the CPU does not have a heatsink. The

router temperature can be lowered by adding a fan to the WRT54G casing

[18]

which can be powered externally or wired into the router's main power. Attaching a small heatsink, such as a video card heatsink, to the router's CPU will also help dissipate the heat.

The CPU can be identified from its Broadcom label.

Some performance issues have been encountered with the Linksys firmware which may cause sluggish or total network failure. This is usually caused by a large amount of

connections clogging the router

[19]

. Installing a third party firmware and increasing the maximum ports setting to allow more connections is the usual solution(in DD-WRT found

under Administration->Management->Maximum Ports).
