答案1

除非uname -a显示你正在使用内核 3.16,否则你的无线网应该在

sudo apt-get install bcmwl-kernel-source
如果你使用的是 3.16,只需将其添加到你的问题中,因为你需要 utopic 版本

根据http://linuxwireless.org/en/users/Drivers/b43/b43 驱动程序不适用于 BCM4313 卡,但现在是时候看看它是否能正常工作,因为 bcmwl 不起作用 sudo apt-get purge bcmwl-kernel-source sudo apt-get install firmware-b43-installer

重启
