Welcome to the Monastery rentacode90

You don’t say where the script is that you are trying to run.
Is it on the server on the Uni machines or is it on your laptop Hard drive?
As pointed out by shmen and swampyankee more information is needed, a lot of Universities run Perl mostly on their Unix machines which may not be connected to a wireless Network.

From past experience I have been able to upload a script to the Unix server by ftp but have been unable to run the same via a wireless connection for the above reasons.

Update
Do you have access to the Sun Secure Global Desktop by an Internet connection, this could give you access to a gnome (Unix) terminal, you could try running your Perl script via that, this would also allow you to check the file location.

Further Update
Is your laptop MAC address registered on the Uni system?
Do you have a Uni log in and password and does it allow access.
