BCM 4311 driver is "activated" but wireless does not work
I installed 11.04 on our Dell laptop. The wireless does not work.
The Additional Drivers window says that "Broadcom STA wireless driver is activated and currently in use."
The lshw command shows network controller BCM4311, configuration: driver=
I ran the lsmod command but it did not list anything that I recognized as a wireless driver.
iwconfig says "no wireless extensions"
iwlist scn says "interface does not support scanning"
rfkill list says "soft blocked:no, hard blocked:no"
When I boot into Windows (dual boot), the wireless works fine.
I have read some good discussion of this kind of problem at question # 157369 and at bug # 732677. I get the impression that the problem is caused by two competing drivers (STA and b43), and that the solution involves fwcutter, but I only know a little bit about computers and don't want to start installing/

I am pretty sure that your wireless adapter is experiencing the following Broadcom driver bug in Ubuntu 11.04:

As I understand it, there are 2 possible solutions for the BCM4311 wireless problem in Ubuntu 11.04:
1) installing b43-fwcutter and firmware-

or
2) manually installing bcmwl-kernel-source (5.60.48.

Wireless now working. Thank you!
I ran: sudo apt-get install b43-fwcutter firmware-
then removed the STA driver at the Additional Drivers window, then re-booted.
@Glen: You are welcome.
By the way: it was smart of you to first ask for advice before starting to muck around with blacklist settings and installing stuff that shouldn't be installed. Some people first muck around before asking for advice and then it takes 10 times longer than usual to get the original issue fixed. ;-)
