在一台旧笔记本上用U盘安装了Ubuntu,无线网卡无法识别,所以记录下解决办法:
查找网卡信息
lspci | grep Net lspci | grep net
得到网卡信息:
Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
安装网卡驱动
1、安装b43-fwcutter工具
wget http://bues.ch/b43/fwcutter/b43-fwcutter-018.tar.bz2 tar xjf b43-fwcutter-018.tar.bz2 cd b43-fwcutter-018 make sudo make install
2、使用b43-fwcutter工具安装驱动
wget http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2 tar xjf broadcom-wl-5.100.138.tar.bz2 sudo b43-fwcutter -w /lib/firmware ./broadcom-wl-5.100.138/linux/wl_apsta.o
