答案1
尝试这个：
sudo apt-get install firmware-b43-installer
sudo apt-get remove bcmwl-kernel-source
它在装有 Broadcom wifi 芯片的 Dell Inspiron 6400 上为我工作。
答案2
编辑文件/etc/modprobe.d/blacklist.conf并在最后输入：
blacklist acer_wmi
重启后就大功告成了。如果你完全从 GUI 进行操作，那么可以通过按ALT+ F2（这将打开“运行”窗口）并在那里输入gksu gedit /etc/modprobe.d/blacklist.conf然后在下面添加此行来编辑文件
rmmod dell_laptop
答案3
打开终端。只需按下键盘上的Ctrl+ Alt+T即可打开终端。打开后，运行以下命令。
sudo rfkill unblock all
