This is related to the Broadcom 43xx problem discussed in the sticky above. Hope this is the proper place to post.
I have a Dell Inspiron 1150 with a Broadcom 4306 card. It worked with wireless fine in previous versions but has not since I installed (clean) version 12.04.
I installed the B43 driver but when I try to install the firmware for it, the system crashes, leaving a long line of script on the screen. Something about "modprobe tainted."
I have a Belkin USB stick that I can reach the Internet with and I suspect it might be causing a conflict.
I could just continue using the USB stick but it irks me that I can't get the card to work as it did before. Have considered getting another card, since they only cost about $9, but I am doubtful that would help.
Any suggestions appreciated.
