Thank you for your help

I also advise you get fully updated over the wired link with:

sudo apt-get update; sudo apt-get upgrade; sudo apt-get dist-upgrade

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:

https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/732677/comments/23

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
