删除附加驱动里的那个STA无线驱动，然后用下面灯方法安装，并删除bcmwl-kernel-source后重启后可用。

 

The Broadcom BCM4311 is a PCIe wireless device widely available in laptops sold by many manufacturers.

• In the terminal the following command will provide the pci:id (pci number)

 

lspci -nn | grep 0280

 

ID Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)

These instructions are written for Ubuntu 11.04.

This card works with the driver b43 and ssb. Proprietary firmware is required which is not provided by default in Ubuntu installations. Install it with:

 

sudo apt-get install b43-fwcutter firmware-b43-installer

Reboot and the wireless should be working.

CAUTION: This pci.id is also claimed by the Broadcom STA driver provided by bcmwl-kernel-source. Installation blacklists b43 and ssb. The driver bcmwl-kernel-source driver wl doesn't work well and b43 and ssb are preferred. To remove the incorrect driver and blacklist, do:

 

sudo apt-get remove -–purge bcmwl-kernel-source
sudo rm /etc/modprobe.d/blacklist-bcm43.conf
