WRT54GL Versions?

    I realize that the WRT54GL is essentially the WRT54G ver. 4, the Linux version which permits Tomato, DD-WRT firmware, etc. to be installed.

    BUT, what are the differences between the versions of the WRT54GL itself, and are they significant with regards to Tomato specifically?

    I need to "clone" a number of WRT54GL routers using the backup .cfg export file, and I'm concerned that differing version numbers will prevent that, much as they did with versions 1-4 of the WRT54G itself.

    What is the current WRT54GL version number shipping from retailers, and when did that version start shipping?

    The situation is complicated by the fact that the version number is not visible from outside the sealed WRT54GL boxes, and by the fact that opened boxes are often not returnable...I have a bunch of these available to me, still sealed, with purchase dates available, but I'm reluctant to start opening them to determine the version number to see if they're all the same.

    BTW, the earliest ones I have access to were purchased from Amazon and Newegg 12/2008. Will they still be same version as what's shipping today?

    You can tell what version the WRT54GL is from the serial number on the box.

    Even between routers of the same model, loading the config backup from another router is not directly going to work. You may be able to get it to work by manually editing the file, but there was a thread a while back where a couple of people tried that without any success.

    Why would you want exact clones of your routers?
    OK: I use a cold spare a hot spare myself.

    Most likely you can diff the nvram-settings vs factory defaults manually.

    Then cut 'nd paste it into the other routers via commandline interface.

    A cold spare is one reason...it's tedious to manually enter the table to forward nearly a dozen ports.

    But, also because I will be setting up a bunch of bridges that will be identical pairs,
    except for the MAC addresses which would have to be entered manually, of course.

    I have successfully used the configuration file between two WRT54G ver. 4 routers, but it failed when trying to use it on ver. 3 hardware, with an error stating it was not compatible.

    Thanks for the information, guys.

    About a month ago there was a thread running between fyellin and me, mostly. He had some pretty good ideas regarding flashing different routers. I volunteered to be a guinea pig, flashed a modded file, and bricked the router (needs DTAG to unbrick, not bothered yet). So not thought any more on this subject until now.

    But if you can locate that thread, it has a lot of information you will find useful. I'll try to paste a link if I find it.

    I'm not a command-line or SSH kind of guy, yet.
    I have only done a backup to create a .cfg file and a restore to import it into another router, via the Administration page in the GUI...seems to work OK if the hardware is the same. Probably would be wise to clear the NVRAM first though, I'm thinking.

    I checked my WRT54GL serial numbers and all are ver. 1.1 so I assume the additional ones I have on order will be the same.

    Now that the WRT54GL routers are finally dropping in price ($54 shipped at both Amazon and Newegg), I am moving forward with a WDS bridge project to make several network cameras wireless...cheaper than buying a bunch of WET54G client adapters which continue to be about half-again more expensive.

    Glad I discovered this forum...some smart people here and everyone seems quite civil!​
