    hi everybody,

    i red that there are two kinds of that particular box on the market.
    now i would like to know how i can find out whether my WRT54GSv4
    is one of the 32/8 or 16/4 devices.
    are there any visible differences on the motherboard, or something?

    I am afraid that most people concur that with the assessment that all the WRT54GSv4 and WRT54Gv4 hardware have the same PCB and memory: 16MB RAM / 4MB Flash

    From evenything I've read, the WRT54G V4 (like mine) and the WRT54GS V4 (apparently like yours) are absolutely identical except for the firmware, which artificially disables the GS features in my WRT54G.

    So, you and I both have the same router. And it's a 16/4 device. If you can find one, see if you can exchange it with one of the older WRT54G units (the ones that do NOT have a "CGN6" serial numbers).



    If you can get to a command line (usually requires aftermarket firmware), you can type "cat /proc/meminfo" at the command line. My 16MB unit reports the following:

    total: used: free: shared: buffers: cached:
    Mem: 14807040 13832192 974848 0 2035712 5746688
    Swap: 0 0 0
    MemTotal: 14460 kB
    MemFree: 952 kB

    EDIT: Fixed command from "at" to "cat". Oopsie.

    pitty, isn't it?
    anyhow, 4mb should suffice for all i need right now

    y, i knew the link... all it's said there is that it looks like a v3 from the inside
    thanks for the commandline tip!
    immediately telneted the thing, but my dd-wrt.v23.std_beta2
    (02.12.05) features no 'at' command.

    ~ # help

    Built-in commands:
    . : alias bg break cd chdir command continue eval exec exit export false fg getopts hash help jobs kill let local pwd read readonly return set shift times trap true type ulimit umask unalias unset wait

    naturally i recognise some of them, but i still don't have a clou how to make it tell me how much mem is has installed.

    Dang cutting and pasting and lazy people (ME, not you).

    That's "cat", not "at". Terribly sorry about that. I'll fix my original post, too.

    In my case, it's not too much of a pity. I get a WRT54G V4, for $50, that can easily be upgraded to a WRT54GS V4 with a firmware change (Thibor instead of Tofu). Of course, I only learned that after I loaded Tofu, and frankly I really don't need GS capabilities.

    In your case, yes, I can see where it is. It would be the same for me if I found out I had acquired a WRT54G V5 for my $50, and I'd be hopping mad. But of course surfing a half dozen stores enptying their shelves and scouring serial numbers (and being scowled at by sales people who can't understand why I'd want one of the OLD ones) prevented that. (grin)

    If you bought it locally, you may want to go back to the store and see if they have a pre-V4 "GS", and see if you can exchange it.

    ah, no prob...
    thanks anyway. brought me back to thinking and i found 'free' to display the used and free memory instead.

    ~ # free
    total used free shared buffers
    Mem: 14060 10308 3752 0 1304
    Swap: 0 0 0
    Total: 14060 10308 3752

    looks pretty much like a 16/4 to me.
    y, maybe i'll try something with a local store, just for the fun of it.
    i bought the thing about a month ago at amazon.

    Yup. "free", "top", and listing all the processes give the same basic data. At one point, I tried to bug Tofu to put free and available memory on the status page, suspecting a memory leak and being too lazy to go into the command line all the time. Fortunately, the memory leak was a false alarm. Someday, though, Tofu may decide it's useful to display available memory. Or maybe not. Either way I'm darned glad he's put the work into this that he has. My $50 WRT54G V4 feels like a much more expensive router now.
