[Ubuntu] Broadcom Wireless STA Driver Activated But Not Currently In Use

来源：互联网发布：高性能服务器端java 编辑：程序博客网时间：2024/06/05 23:57

我使用的是Kubuntu 12.04，无线信号很不给力。然后按照http://forum.ubuntu.org.cn/viewtopic.php?t=202388中说的方法装了Windows驱动，发现不起作用后卸载了。结果每次重启都检测不到原先的无线网卡驱动，additional drivers中提示Broadcom Wireless STA Driver Activated But Not Currently In Use，必须卸载重装才行，但是重启后又是同样的问题。Google了一下，在墙外找到一篇博文http://techdc.blogspot.com/2011/02/ubuntu-broadcom-wireless-sta-driver.html（需翻墙），照做可以解决问题，就是不知道每条命令是什么意思。

1. Optionally u can try these commands first.. just to check the connection

lspci -nnlshw -C Networklsusbifconfigiwconfigsudo iwlist scan

Now run the following commands..

sudo modprobe -r b43 ssb wlsudo modprobe wlsudo ifconfig eth1 upsudo iwlist scan

2. Blacklist ssb. Run the following command

echo blacklist ssb | sudo tee -a /etc/modprobe.d/blacklist.conf

3. Edit rc.local and add the following code at the end.

sudo vi /etc/rc.local

and add this just before "exit 0"

modprobe wl

Now just reboot... the problem should be gone :)
