我在一台全新的 Dell XPS 13 9365 上全新安装了 Ubuntu 16.04,但无线无法使用(但以太网可以)。我查看了许多论坛帖子以寻找可能的修复方法,并尝试了许多方法但均未成功,包括:
- 清除/安装
bcmwl-kernel-source
sudo service network-manager restart
- 禁用安全启动
- 使用专有驱动程序和
sudo apt-get upgrade
但没有任何效果。以下是可能相关的信息:

您的设备在内核版本 4.8 之前不受保护。Ubuntu 16.04 使用内核版本 4.4。
你可以安装 Ubuntu 16.10,也可以将现有安装升级到 4.8 内核。在后一种情况下,通过其他方式连接到互联网并安装 4.8 内核
sudo apt update
sudo apt install linux-generic-hwe-16.04-edge
您还应该删除不正确的 Broadcom 驱动程序:
sudo apt-get purge bcmwl-kernel-source
您还需要此设备的固件
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.161_all.deb
sudo dpkg -i linux-firmware_1.161_all.deb
重新启动后无线设备就可以工作了。
