Auto Login to a Wireless Network (Browser)

Topic

New Reply

My school’s wireless requires people to accept a certificate to use the net. This certificate is kind of wonky so I have to use Opera to (or IE but that’s not happening) to accept it. Firefox 3.6 and earlier it just wouldn’t connect. Firefox 4 just crashes. What I want to do is have my computer automatically run a script (which I can figure out how to right) when it detects that I’m connected to a certain SSID but don’t have an internet connection. Of course if someone knows an easier way to automatically login to a browser system that would be useful as well.

To fully clarify I’ll list the steps to connecting to the internet:
My computer automatically connects to the SSID LC3

It pops up a little message that says something to the extent of more login info is needed.

I Open Opera (for as I said my default browser just crashes)

I open a new URL so I to trigger the login

I accept a javascript usage dialog

I click to accept the terms of use.

I’d recommend using AutoIT to automate the login procedure from the point the message pops up requiring additional information to connect. Install AutoIT and the SciTE editor packages to provide a development environment.

Here’s a trivial script I wrote as an exercise as an example of some of the capabilities of AutoIT. Run this script while viewing this forum topic to get the information on-screen and posted to a file in your Documents folder. Tested on IE and Chrome.

If you want to stay “native” (that is don’t install another program) then VBScript is probably capable, but I don’t have a useful example to offer there.

If it is an SSL certificate you could get a free one from StartSSL. Then it won’t be wonky.

cheers, Paul

I was actually thinking of using AutoIt anyway but I don’t know how to make it start when it detects I’m connected to LC3 but not the internet. I haven’t read your example script yet but, I’ll definitely have to check it out (and the SciTE package as well).

I’m not honestly sure as I’ve just gotten used to clicking my way through. I’ll have to check it out. If that does work it’ll save me the work with AutoIt though as I said before I’ll still check the script out as I’m always willing to learn.

P.S. Sorry for the weird bold script. I used a copy paste Operation for the names and it caused that weird bold thing to happen (Pressing the bold button/pressing ctrl+b does fix it). I’m also assuming you’ll see the bold as I’m seeing it…Weird

I just went to the startSSL link and it looks like it’s for giving my own website a certificate. It doesn’t mention being able to auto-login (which is what I’m looking for).
