-[Comment: I've encountered ver.6 WRT54G (SN:CDFD*) & WRT54GS (SN:CGN9*) in which vxworks_prep_v03.bin is rejected by the "web gui" upgrade, with little/no relevant docs available. Where I have found reference to the problem, there are no sollutions. A perfect example is [http://www.dslreports.com/forum/remark,16884929~mode=flat Sureshot's question], and TheScorpion's answer: "The upgrade fails because you aren't uploading a file that the GS will recognize as a valid firmware file."+

After several people asked about the GS, I revised the tutorial on how to upgrade a GS as well. More or less the same process with 1 different file.+See [[Linksys WRT54G v3.0]] page.

-After flashing my WRT54GL to v23 SP2 I was unable to access the web administration page at first. It turned out that the httpd process was crashing every time I tried to access it. I found this workaround in the forums and it fixed the issue:+
- nvram set language=english +
- nvram commit +
- reboot+
-After the reboot my httpd was back and running. I suspect that the initial error was caused because I hadn't explicitly reset to factory defaults (I assumed that the just-out-of-the-box router would already be at default).

-I successfully flashed a WRT54GL Ver 1.1 loaded w/stock Linksys firmware with DD-WRT standard version (V23sp2)using the Installation Tutorial above. The only slight difference from my experience than the tutorial was I did not see any success or fail message, It came up with a "continue" button and when clicked got a blank screen in the IE browser. Rebooted the PC to clear the old IP out of PC's DNS and upon completed reboot was able to login to the new DD-WRT screen. The only other devation was I bypassed the "Mini" version and went straight to the "Standard" (by accident) with No problems.+

-Today I purchased a 'GS V4 not having read this note previously. It flashed V23 standard perfectly first time from the specific file (dd-wrt.v23_wrt54gsv4.bin) therefore there may be some additional factors influencing this) - I hope this is useful feedback+
-''[Comment added 12/01/06 by Mart]''+See [[Linksys WRT54GS v1.1]] page.
-I just purchased a GS V4 too. After reading bigbloke's note, i decided to try skip the warning and directly flash V23 VPN from the (dd-wrt.v23_vpn_generic.bin) file without any problems too. I simply followed the "right way to flash" instructions step by step. Looks like the warning mentioned above does not apply with this version.+

-I too can confirm that it can be upgraded directly to standard version. Even after reading this, I experimented upgrading my WRT54GSv4 directly with v23 SP1 standard image without any problem. May be stated limitation is firmware version dependent. At the time of upgrade, my linksys stock firmware version was 1.5.2.+

[edit] Gv7.0

WARNING The WRT54G v7 uses an Atheros AR2317 chip, has 2MB ROM, 8MB RAM and runs VxWorks. It is not supported by DD-WRT as the WRT54G v7 isn't Broadcom based. The WRT54G v7 will probably never be supported

See Linksys WRT54G v7.2

[edit] Gv8.0 & v8.2 (see below for v8.1)

See Linksys WRT54G v8.0 & v8.2 page.

[edit] Gv8.1

The WRT54Gv8.1 router already has a Linux CFE in the flash. There is no need for running any prep or killer file before the initial flash.

This model also has a 128K compressed CFE so it will load micro_plus and micro_plus_ssh directly. Initial flashing of this model requires a modified file with the proper header. You can obtain this file here. After this file is loaded you can then upgrade to any micro_generic.bin file....or one of the micro_plus, micro_plus_ssh mentioned above.

See Linksys WRT54GL page.

[edit] WRT54GS

DD-WRT supports versions 1 through 6 of the WRT54GS router. (Note that later versions have less flash memory and may require micro versions of DD-WRT.) Versions 7 and 7.2 must use the micro (not the mini) version.

[edit] GSv7.0 and v7.2

See Linksys WRT54GS v7.0 & 7.2 page.

[edit] Clock Speed and Overclocking

The standard clock speed of a WRT54G(S) v2-v6 is 200 MHz. DD-WRT allows overclocking the device to up to 300 MHz for v2-v3 and up to 250mhz for v4-v6. It is also possible to underclock, which may be useful for troubleshooting crashes which may be caused by overheating. Newer Linksys firmware overclocks some models of the WRT54GS to 216 MHz, to prevent instability issues inherent in the 2.x versions.

The WRT54G(S) v4-v6 and WRT54GL v1.x have a BCM3302 v0.8 processor instead of a BCM3303 v0.7 with previous models.

WRT54GL v1.1 is stable when overclocked at 250MHz, with no extra cooling. Your mileage may vary.

For information on running a v4 series greater than the CFE imposed maximum of 250mhz, please see [Increased overclocking through CFE modifications] (technical).
