WRT54GS Change mac without config page? :confused:

    Hello, i'd like to be able to change the MAC address of my linksys WRT54GS (v2) (firmware 4 something) without having to use a web browser. so if anyone knows of a way to change the MAC address of the router without actually having to goto the routers config page, change the digits, and hit apply that would be grand! open to any and all suggestions.

    ok after abit of reading around, the easiest way to send the router commands is through tftp?

    whats the best (most stable fastest etc) firmware to use that allows for commands like "nvram get il0macaddr" and "nvram set il0macaddr" over tftp (or w/e)

    Well if you are happy with Linksys firmware you will be familiar with Hyperwrt Thibor using a web based "run command" or Telnet command line interface (which can be used with SSH but I've not tried!). AFAIK tftp is just for loading firmware files after boot-up with only a very few specific commands.


    nvram get il0macaddr

    works fine, I'm not going to try the "set" as I do not know why you would want to it - do you have to reboot to take effect? You also need to give "nvram commit" to save the params to flash (may work without as some other task may do it for you!)

    Thanks for the reply, i'll look into "Hyperwrt Thibor" later tonight/tomorrow when i feel upto reflashing my router.

    I'll be using the set command to change my mac address every now and then (my cable modem can learn upto 32 mac's before it needs to be rebooted) though im certian you'r right with the commit command also being needed to make the router actually use the new mac.

    overall the whole point of this is to change my IP address. having a way to do all this through commands rather then through the web dialog only helps me shave the 30seconds it takes to open a browser, type in the router ip, and manually change the mac.
