Wifi 驱动程序无法运行

Wifi 驱动程序无法运行

大约一周以来,我一直在尝试让笔记本电脑上的 WiFi 驱动程序正常工作,但每个视频和线程都没有帮助我。我知道我需要使用 sudo apt-get install b43-fwcutter,但每当我在终端中输入它时,我都会得到:

Reading package lists... done 
Building dependency tree
Reading state information... Done 
E: Unable to locate package b43-fwcutter
A suggestion was to put lspci -vvnn | grep 14e4 in terminal:

09:Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM5755M Giga bit Ethernet Pci Express [14e4:1673] (rev 02)
0c:00.0 Network controller [0280]: Broadcom Corporation Bcm4311 802.11b/g WLAN [14e4:4311](rev01) 
sudo apt-get install linux-firmware-nonfree:

您的无线网卡需要专有固件才能工作。若要在没有网络连接的情况下安装它,请将此文件下载到您的桌面。https://dl.dropboxusercontent.com/u/58267392/b43.zip右键单击它并选择“在此处提取”。现在打开终端并执行以下操作:

sudo mkdir /lib/firmware/b43
sudo cp Desktop/b43/*  /lib/firmware/b43
sudo modprobe -r b43 && sudo modprobe b43

您的无线网络现在应该可以正常工作了。我建议您在完成此操作后提出一个新问题,以使您的以太网正常运行。
