Hello,

I have installed 11.04 on a Compaq Presario laptop and the following is the output from the sudo lshw-C network command.

  *-network UNCLAIMED

I think that your BCM4311 wireless adapter is experiencing the following Broadcom driver bug in Ubuntu 11.04:

https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/732677

I suggest installing bcmwl-kernel-source (5.60.48.36+bdcom-0ubuntu5) from maverick (Ubuntu 10.10) using gdebi

Solution is described here:

Then reboot your PC and run the following commands to enable your wireless adapter:

rfkill unblock all
sudo rfkill unblock all

Then retest wireless using NetworkManager

Hello All,

Many thanks for all the support. I installed the 10.10 driver and have locked it in the Synaptic. A reboot and it works.
