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

Ubuntu 12.04 solves the failure of installing the Broadcom STA wireless NIC Driver. First, open the terminal and enter: ls-nn | grep 0280 to view the PCI of the NIC. ID. Mine is: 03: 00.0 Network controller [0280]: Broadcom Corporation BCM43227 802.11b/g/n [14e4: 4727]. Then, enter sudo apt-get install -- reinstall bcmwl-kernel-source. After installation, enter sudo modprobe wl www.2cto.com. If no warning or error is reported, reinstall the wireless driver, it should be ready for normal use! 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 author monkey paper
