我无法在 Hp Compaq nc8430 - ubuntu 12.04 上安装 wifi 无线驱动程序 bcm4311 
tony@tony-lap:~$ lspci -vvnn | grep 14e4 
08:00.0 Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM5753M Gigabit Ethernet PCI Express [14e4:16fd] (rev 21) 
10:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)

这是我安装 bcm4311 的操作

//删除旧的驱动程序

sudo apt-get remove bcmwl-kernel-source

//安装b43驱动程序

sudo apt-get install b43-fwcutter firmware-b43-installer
sudo gedit /etc/modules

在文本文件末尾添加“b43”（不带引号），注意每行只能使用一个模块。

sudo gedit /etc/modprobe.d/blacklist.conf

添加不带引号的“blacklist wl”以防止在启动时加载错误的模块。

sudo reboot

点击系统设置 → 点击“附加驱动程序” → 选择 Broadcom 标准驱动程序 –> 点击激活 点击激活附加驱动程序后出现错误，请帮忙！！！！！！

这是输出。

答案1

对于此设备 14e4:4311，通过“附加驱动程序”安装 Broadcom STA 驱动程序是不正确的。它添加了许多所需驱动程序的黑名单。删除驱动程序是不够的。为了删除黑名单，必须清除它：

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree

重新启动后，您的无线设备应该可以正常工作。请远离“附加驱动程序”。

答案2

基本上你的硬件已关闭。尝试一下笔记本电脑上的物理开关。也可以尝试

rfkill unblock all命令。该按钮可能是“fn+f12”或笔记本电脑上的某个物理键。
