我在配有 Intel 8265 wifi 卡的联想 T470p 上运行 Kubuntu 17.10。这是我的 lspci：

这是我的 rfkill 列表：
van@t470p:~$ sudo rfkill list

Hard blocked: yes
4: hci0: Bluetooth

以下是 dmesg 的输出：
van@t470p:~$ sudo dmesg | grep iwlwifi

我的 /lib/firmware 中似乎没有 iwlwifi-8265-33 或 iwlwifi-8265-32：
van@t470p:/lib/firmware$ sudo find ./ -name "*8265*"
./iwlwifi-8265-22.ucode
./iwlwifi-8265-21.ucode
./iwlwifi-8265-27.ucode
./iwlwifi-8265-31.ucode
这可能是为什么它在启动时被“硬锁定”的原因吗？
真正令人恼火的是，在我必须进行全新安装之前，一切都运行正常。
我尝试了显而易见的 FN + F8 和 FN + F10 组合键。不确定这台笔记本电脑上是否还有其他组合键可以打开/关闭 wifi。
我的问题是：我该如何消除“硬阻止”以便启动我的 wifi？
