Can't connect to wireless at school.

Hi,

I'm able to connect to my connection at home but not at school. When I was running Windows XP on this machine, I had no problem connecting any where. I tried several of the solutions from other threads, but none seems to work for me. I also tried 'sudo apt-get --reinstall install bcmwl-kernel-source' that also didn't work. When I go to System -> Administration -> Hardware Drivers, it says "no proprietary drivers are in use on this system". Here is my lspci output:

I am using wireshark for one of my projects.
I am using a command some thing like this
under root previlege from wireshark folder I am running the following command from the command line
wireshark -i eth0 -f "host 192.168.2.3" -k -c 1000 -w "output.txt"

It works fine from the command line but running from a java application causes me an error
it throws me an error
at double quotes
I even tried using \ but of no use
like
String cmd = "wireshark -i eth0 -f \"host 192.168.2.3\" -k -c 1000 -w output.txt"
If i did not put quotes for output.txt it works fine but it is not the same case for the -f option, even though i tried several ways to include quotes but of no use...

Merry Christmas
