Ubuntu 12.04 solves the Broadcom sta wireless NIC Driver Installation failure Solution

First, open the terminal and enter: ls-nn | grep 0280 to view the PCI. ID of the NIC,

My website is: 03: 00.0 network controller [0280]: Broadcom Corporation bcm43227 802.11b/G/n [14e4: 4727]

Enter sudo apt-Get install -- reinstall bcmwl-kernel-source. After installation, enter sudo modprobe WL.

If there is no warning or error, reinstall the wireless driver and you should be able to use it normally!

PS: This method has been verified only when the PCI. ID of the wireless network adapter is 14e4: 4358 and 14e4: 4727. Other IDs are not necessarily applicable!

This method I saw on the Ubuntu official website, the original link: http://ubuntuforums.org/showthread.php? T = 1967515
