Reinstalling LL after losing wifi due to installing updates

[bobw]

Unfortunately, that hasn't worked.  I also tried going back to the 4th command, then the 5th again, but still no success.

The output from the inxi -nz command is now:
Network:  Card-1: Broadcom BCM4311 802.11a/b/g driver: b43-pci-bridge
          IF: N/A state: N/A mac: N/A
          Card-2: Marvell 88E8040 PCI-E Fast Ethernet Controller driver: sky2
          IF: eth0 state: up speed: 100 Mbps duplex: full mac: <filter>

I've looked at the page suggested by rokyntji:
https://help.ubuntu.com/community/WifiDo...er/bcm43xx

Should I try something from this page:
sudo apt-get --reinstall install bcmwl-kernel-source

This is for Ubuntu 12.04-12.10, so may not be right for LL2.0?
