Dell Lattitute D620 wifi not work with ubuntu 11.04

[marcoslai]

I just bought a used laptop - Dell Lattitute D620,installed 32bit Ubuntu 11.04 gnome,found my wifi is not working.
'Additional Driver' show that restricted driver is activated & in use,but I switch my wifi hardware button to 'on',the light didn't on,and there's only 'Auto eth0' sho in network manager,NO wireless option.........
How to fix it?
Found a sticker at the bottom of laptop showing my wifi chip is Broadcom brcm94311mcg.

+1, wifi doesn't work on my d620 either. Worked fine on 10.04 and 10.10. I guess I'll be downgrading...

[josephmills]

could we all see a

sudo lshw | grep 14e4

thanks

[mlabowicz]

PCI (sysfs) shows up for a few seconds and then I'm dropped back to the shell prompt. No other output...

sudo lshw | grep 14e4
