我刚刚安装了带有 4.10 内核的 Ubuntu 16.04 桌面版，但无法访问 wifi。我使用以下命令安装了 Broadcom 驱动程序。

并且无法访问 wifi。
答案1
正如您看到的lshw，您根本没有 WiFi 卡。
解决这个问题的方法是购买一个并安装它。
答案2
您是否尝试过重新启动网络管理器？以下是代码
sudo service network-manager restart
如果不起作用，请使用以下方法安装缺失的固件
cd /lib/firmware
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-7260-17.ucode
然后重启进入内核 4.10
iwlwifi-7260-17.ucode 文件不在 14.04 的 linux-firmware 包中
