我需要一些帮助才能让我的 wifi 卡正常工作。我从 w7 迁移到 Ubuntu 16.04 LTS，问题就开始了。
我的无线网卡已在 BIOS 设置中启用，并且我已经按 Fn+F8 将其打开。
当我查看 lspci -knn 时，我得到了这个：
02:00.0 Network controller [0280]: Intel Corporation Centrino Advanced-N 6230 [Rainbow Peak] [8086:0091] (rev 34)
Subsystem: Intel Corporation Centrino Advanced-N 6230 AGN [8086:5201]
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
检查 dmesg | grep iwlwifi 我发现此消息：
RF_KILL bit toggled to disable radio.
我怀疑这表明了我所面临的问题。
我已经尝试做过一些序列，例如：
rmmod iwldvm
rmmod iwlwifi
rfkill unblock all
modprobe iwlwifi
modprobe iwldvm
我的“rfkill list all”输出是：
0: Toshiba Bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
2: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

这是我当前的内核版本：

根据这个页你可以循环通过 Fn+F8 连接 wifi 和蓝牙。
您可以尝试提到的解决方案吗这里？
The thing which solved my case was setting the wifi ON using hardware switch.
Try it: Boot into ubuntu in recovery mode and select enable networking
Reboot and all is done. I then had Hard blocked: no and my wifi started working
