hello, i am trying to run the linux distribution Kubuntu on my inspiron 1520 laptop. When i run Kubuntu from a live cd, after a short period of time, it recognizes a proprietary wireless driver that needs to be installed before i can connect to the internet (duh). Problem. when i install kubuntu via a hard disk partition, it will not recognize the driver, even if i use the start menu to search for proprietary drivers. this has me stumped. PLEASE HELP!!!!!!!!!!!!!!!! 
ps. the driver is a Broadcom b43 wireless driver.
What’s the last line of output for these:
/sbin/lspci
/sbin/lspci -n
edit: open a terminal and try them and copy the last line of output for each of them

Probably it was not installed by default and so must be on the CD (live CD).
So you must reload it from the CD.
Ubuntu (and Kubuntu) will automatically sense and mount a CD for you.
I suggest that you do this (mount the CD) and then install the driver.
Since you are having access to the web, you can also search for a specific driver on the web.
