    Is there an existing wireless router linksys WRT54G script out there that
    will run from Windows XP and hit the 'connect' & 'disconnect' button?

    For example, I'd like to disconnect my wireless router (firmware 1.02.0) by
    clicking on a single shortcut to replace the multiple button presses today.

    That shortcut would (perhaps using wget or some other idea):
    1. Connect to the wireless router IP address (
    2. Log in with a blank username & enter 'letmein' as the password
    3. Navigate to the "Status -> Router" Linksys WRT54G web page
    4. Press the "Login Status = Disconnect" button

    A similar shortcut would reconnect on demand.

    Is "wget" the best way to accomplish this?

    I can't believe I'm the first person to need this so some kind wireless guy
    must have done this already. I googled for "linksys wrt54g connect script"
    and found something called "slackware" in addition to "wget" but I'm not a
    programmer so I would like to start with an existing script that does
    SOMETHING like hit any button on the Linksys WRT54G router. Once I have
    that, I can probably modify that program to do what I want.

    I did find
    interesting but I did not understand most of the detail (I have a lot to

    Does anyone have a script that runs on windows that will connect to
    https://192.168.x.y to then hit a button on the Linksys WRT54G router?

  2. Hi
    Routers are propriety devices there is No one universal way to control them.
    As a result you cab expect Windows as an OS to be programmed to control
    every Independent 3rd party device.
    If it really important you can learn simple scripting, or pay some one to do
    If you just want to disconnect a computer from the Router you can use the
    IPCONFOG /release command.

  3. Sure. There are several Windoze "automation" tools. The one I like
    to use is the ancient "Macro Recorder" from Windoze 3.1. However, I'm
    not going to recommend this because of its age.

    More modern incantations can be found at:
    <> ($23)
    and so on. Search Google for "macro recorder" or "keystroke mouse
    recorder". Lots to choose from.

    You start the recorder, do whatever it takes with your mouse and
    keyboard, stop the recorder when done, and save the macro. If you
    want to repeat it again, just run the macro. Simple.

    Another way to do this is to install DD-WRT or OpenWRT on your WRT54G,
    and use various shell or expect scripts to turn the router on and off.
    The command to turn on/off the WAN connection could be:
    ifconfig eth1 up
    ifconfig eth1 down
    or something like that.

    Hi Jack,
    I want to disconnect the router from the isp (not the pc from the router).
    I dug some more and have some perl scripts (whatever perl is) and will see
    if they will run on Windows.

    Apparently they need to know the name of the Linksys WRT54G button. I
    viewed the page source at and I think
    that the button is called "connect" and then "disconnect".

    I'll keep digging and asking questions and posting the answers as I find
    them until we have a Linksys WRT54G script that runs from Windows to
    a) Log into the Linksys WRT54G router
    b) Navigate to the page
    c) Press the disconnect button
    d) Wait five or ten seconds
    e) Press the connect button

    This refreshes with a new IP address.

    Hi Jeff,
    I know from googling that you are a God on this here newsgroup so I
    appreciate your help even if I'm not quite sure how to install "DD-WRT".

    I'll look it up and hopfully post an answer so the next guy can press a
    button to log into the Linksys WRT54G router, navigate to the status router
    page, press the disconnect button, wait five seconds, press the connect

    This will automatically get a new IP address (at least in my setup it does
    when I do this manually).

    Hi Jeff,
    Do you think this perl script modified to hit the disconnect & connect
    button will work? I'm googling for just how I would change the script

    So far, I see the following changes needed:
    1. I will google to see how to give the "null" set (blank?) as a login
    2. I need to figure out how to press the disconnect button

    Before I dig further, is this script below a good place to start in order
    to create a Windows script that disconnects the Linksys WRT54G wireless
    router from the ISP from a wireless portable PC client?


    #!/usr/bin/perl -w
    use strict;

    # check out this documentation:
    # first, the cookbook
    # the LWP reference
    # oh but this is JUST what we want

    my $adr=''; # talk to this
    my $user='root';
    my $pass='letmein';

    # make a User Agent
    use LWP::UserAgent;
    my $ua = LWP::UserAgent->new;

    # make a request object
    # fill in the button name and value from
    # looking at the page source.
    # DD-WRT puts out a complicated page with Javascript that
    # I don't understand how to deal with, so this doesn't work,
    # but in principle (if I knew what to put in for action and reboot)
    # it should.
    my $req = HTTP::Request->new(POST => $adr,

    $req->authorization_basic($user, $pass);

    # send the request
    my $result = $ua->request($req);

    # print the result
    print $result->as_string;

  7. How to install DD-WRT:
    Note that there are different firmware images and proceedures for the
    various WRT54G hardware versions. You didn't specify yours. Check
    the serial number label.
    I believe I suggested a method using a "macro recorder".
    Maybe. Most ISP's don't work that way. If you disconnect, the next
    time you reconnect, you'll probably get the same IP address. That's
    to keep their log files sane. Notable exceptions are the ISP's that
    change IP addresses to discourage setting up servers.

    I question why you would need to change IP's? If this is some
    variation on trying to become anonymous or hidden while on the
    internet, you're on your own.

    I'm not a Perl programmer, so I can't help you learn Perl via usenet.
