我尝试下载 Broadcom STA 无线驱动程序，它在附加驱动程序中显示为已激活，但似乎没有什么作用。请帮忙！
答案1
首先，在终端运行：
sudo apt-get install linux-headers-$(uname -r) build-essential
删除 Broadcom 的内容可能是一个好主意：
sudo apt-get remove --purge bcmwl-kernel-source
从下载驱动程序Realtek 网站（RTL8188CE）
向下滚动到 Unix(linux) 部分，确保下载了适用于内核 2.6.24（及更高版本）的驱动程序。选择离您最近的镜像，并将下载的存档保存在您的Downloads文件夹中。右键单击并选择“在此处提取”。
在任期内
cd ~/Downloads/rtl_92ce*
sudo su
make install
exit
等待奇迹发生。重启。希望 Wi-Fi 能正常工作。报告结果
