Unable to connect to school wireless

[tuan_b918]

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:

As far as I can see you have the correct configuration for driver and interface... you can check the wifi networks available with:

$ iwlist scan

did you see the essid of the network? ... in that case, maybe it's just a network security configuration problem. Do you know the encryption type of the school network? What are the steps that you're following to setup the network? ... also, post the output of 'dmesg' command plz.
