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。
lspci -nn lshw -C Network lsusb ifconfig iwconfig sudo iwlist scan
sudo modprobe -r b43 ssb wl sudo modprobe wl sudo ifconfig eth1 up sudo iwlist scan
2. Blacklist ssb. Run the following command
3. Edit rc.local and add the following code at the end.
Now just reboot... the problem should be gone :)
