- | DD-WRT supports versions 1 - 6 of the WRT54G, WRT54GL and WRT54GS hardware. WRT54G(S) v5-v6 series are supported in v23 SP1 and above "micro" builds, but require you use a special flashing procedure (see 'flashing v5 - vxworks killing'). DD-WRT does not currently support the WRT-54GX, Linksys's MiMo version router. DD-WRT is also reported to work on the WAP54G, but your mileage may vary. | ||
- | |||
- | The WRT54Gv7 uses an atheros chip, runs VxWorks, and has 2MB/8MB ROM/RAM. It is not supported. If someone wants to donate a unit to db90h (mail jeremy@bitsum.com) he can work on it. | ||
- | |||
- | '''WARNING:''' | ||
- | v22 isnt compatible with v4 and newer routers and GL. They are different. Only v23 and newer will run on this model. | ||
- | You would otherwise have to 'un-brick' your router ([http://www.linksysinfo.org/portal/forums/showthread.php?t=47259 Revival Guide method]) | ||
- | |||
- | ''NOTE1: '' | ||
- | Additionally the stock firmware from Linksys on the WRT54G v4 and WRT54GL won't accept a firmware image over 3MB in size (you will get the error: "Upgrade are failed!"(sic) if you try) so you will need to flash the mini version of DD-WRT onto the router BEFORE flashing the std or voip versions. (Remember to hold reset button for 30 sec after flashing mini version.) | ||
- | |||
- | ''NOTE2: '' | ||
- | The WRT54GL Ver 1.1 stock firmware will accept a firmware image of at least 4MB in size; Flashed the memory with DD-WRT standard version (V23sp2). Do not see any success or fail message, however when completed 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. | ||

NVRAM
NVRAM (non-volatile RAM) is the place where the permanent settings are stored. On the command line you can view the NVRAM's content with
nvram show
A variable is stored/changed by issuing
nvram set <variable_name>="<value>" nvram commit
You'll need to reboot to get the (changed) NVRAM executed.
