    Is there firmware that will allow me to increase the range of allowable subnet values in the WRT54GS ver 2.0? i'd like 255.255.0.0 to match my other routers rather than switching all of them to 255.255.255.0

    if you cna't do it from the web interface, you can install a custom firmware and do that from the console with ifconfig.

    Any suggestions on which custon firmware to use? Is it's interface different than Linksys i.e. doesn't show other subnets.

    You can't use ipconfig with the linksys firmware? Would ipconfig change the subnet mask in the computer or the router ?

    pretty much any custom firmware should do, someone may have fixed the web interface to accept larger subnets, otherwise you can ssh into the router and use ifconfig to change the subnet mask on the interface on the router itself.
    You can't use ifconfig on the stock linksys firmware becuase you need a console login to do it.

    Just be aware by increasing the number of allowable devices does not allow you to support a larger number of devices, these are designed for home ans soho use and will not support large numbers of simutaneous users. That is why they stop working with p2p. Go to the commercial routers and switches.

    He might not have a class B worth of devices, in fact I highly doubt he does, but it could be just the way his network is layed out, he didn't specify...

    I have rorters from three manufactuers in use as sitches or modums. They all are 255.255.0.0

    It is just slightly irritating that only Linksys, out of all of them, restricts the subnet mask that can be used.

    I'll probably change all the others to 255.255.255.0, rather than change to a custom firmware for that reason only.

    I assume changing is as straight forward as downloading the firmware and then "updating" it on the router. If it fails, can you use a factory reset to go back to Mother Linksys?

    well the updatring part is that simple you just use the firmware upgrade function of the web interface to install the custom firmware...
    If it fails due to a bad bin nothing will happen, if it does update then a reset will just clear user settings the firmware is stored in flash and will require that you use the upgrade functionality again to flash the linksys firmware again.

    If any of them would let me increase the subnet mask options, which one is the easiest to deal with and the most stable? What would anyone recomend?

    dd-wrt is supposed to be pretty easy, i'm not 100% is you can change the subnet beyond a single octet, wifibox has that option in the subnet mask... but it's not being updated anymore..
    you can do it via the shell on any of them though
