dbus-scripts allows that. Install this package, and create a file called /etc/dbus-scripts.d/wlan containing

/usr/local/bin/myscript * * com.nokia.icd status_changed * WLAN_INFRA CONNECTED

And the script will run whenever you connect to a WLAN (infrastructure mode only not for ad-hoc connections).

You can replace the third star with connection id of your university connection, so the script will only run when connected to university network, not to any network.

There is a GUI for dbus-scripts, if you don't want to create the file by yourself, which is called dbus-scripts-settings.

Both packages are available in extras-devel and in my repository (see my signature).

curl is available in SDK repository, but there is also wget in extras.
