Debian wifi硬阻塞，僅在暫停後工作
我的系統是 ThinkPad L380 上最新的 Debian stretch (9.4)，它有一個 Intel® Dual Band Wireless-AC 8265 卡。啟用/禁用 wifi 的特殊鍵有效，但不會更改硬阻塞條件。
rfkill list all產生以下0: hci0: Bluetooth Soft blocked: yes Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: yes
rfkill unblock all不會改變任何東西。

從 debian stretch 升級到 buster（測試）版本為我解決了這個問題。
編輯：如果您不想升級到測試發行版，還可以選擇通過stretch-backports安裝更新的核心。相應地更新我的之後
/etc/apt/sources.list，我安裝了最新的可用核心，wifi 現在可以在啟動時工作。可能還需要安裝iwlwifi 的 backports 版本。總之：問題是由於核心過時造成的。
