Is the current WRT54GS still running Linux or VxWorks

    With the change over of the 54G from Linux to VxWorks I am now considering moving to the 54GS model. However I am worried that the latest 54GS version is either now, or in the near future, going to use VxWorks also.

    Anyone bought a GS lately? What is the latest version in the stores? Has anyone reflashed the firmware in the latest version?

    This might be a good option as I have a feeling the 54GL will be vaporware.

    All the current GS (including v4) are running Linux. Don't know for the future.

    Amount of RAM

    Read somewhere that WRT54GS Version4's ship in two types: one with 16MB RAM / 4 MB Flash and one with 32MB RAM / 8 MB Flash

    How do you know what type you're looking at standing in the shop?

    Something to do with serial numbers?

    Wow... I've read so many theories about WRT54GS v4. Some say it run linux, others say VxWorks. Some say the RAM is downgraded to 16MB, others say no. Some people say only the RAM is cut in half, but the Flash is still 8MB.

    There's already sold *many* thousands of this model, how come there's so many theories?

    Who and what to believe?

    All GS's run Linux currently. There are no VxWorks versions(yet). Version 5 of the "G" model does run VxWorks(and has only 8/2mb for it's memory).

    As for the memory, it seems most of, if not all of the GS V4 produced NOW have only 16/4mb for it's memory. However, some have said they have V4's with 32/8 for it's memory. My guess is that early production runs may have had 32/8 memory but no longer do. This is just speculation on my part tho.

    I have flashed both DD-WRT and Thibor's HyperWRT onto a V4 "G" and a V4 "GS". That's right, both can run speedbooster because it is exactly the same thing.

    Yes, there are some running VXworks, but you can flash a small "loader" firmware such as DD-WRT V23 Mini Generic, and then you can migrate to the full version of DD-WRT or you can use Thibor's HyperWRT for the "GS" on any V4.

    The V4 refuses to load firmware larger than a certain size, but this is a firmware limitation. Once the origional firmware is wiped out, the limitation is gone.

    If you are mail-ordering, by all means choose the "GS" and "GL" versions. However, if you are shopping retail stores, just find a Linksys WRT54G that doesn't have CDFB as the first four characters of the serial number printed on the back of the box--and then you can avoid the V5 hardware.
