Lenovo IdeaPad S540 14IML 和 Ubuntu 18.04 出現 Wi-Fi 適配器未找到錯誤

我最近購買了一台 Lenovo IdeaPad S540-14IML，配有無線網卡「Intel(R) Wireless-AC 9560 160MHz」。我已經安裝了 Ubuntu 18.04LTS，儘管 WiFi 在 Windows 10 上運作良好，但在查看 WiFi 設定時，我收到了經典的「未找到 WiFi 適配器」訊息。我已經嘗試了在不同線程中找到的許多可能的解決方案，但都無濟於事，所以我重新安裝了 Ubuntu，希望各位好心人能幫我一把。

到目前為止我嘗試過的一些方法：

- 關閉Windows快速啟動

- 將 /lib/firmware/ 中的相關 umod 檔案替換為 Intel 9560 的最新固件，均來自 Intel 網站 (https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-io/wireless-networking.html）如果失敗的話，來自 git (https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/stats/iwlwifi-9000-pu-b0-jf-b0-34.ucode），然後輸入“modprobe iwlwifi”

- 它不是如上所述的 RealTek 無線卡，但我嘗試從以下位置安裝驅動程式https://github.com/tomaspinho/rtl8821ce無論如何，儘管我已經重新安裝了 Ubuntu，這樣這次失敗的嘗試就不會弄亂任何東西

-檢查 rfkill 清單中的區塊（沒有）

- 全面更新Ubuntu 18.04

-這不是全球連接問題，因為我可以透過手機透過藍牙在筆記型電腦上使用互聯網

以下是一些可能有用的輸出：

感謝您提供的任何幫助，我已經使用 Ubuntu 十多年了，我真的寧願避免回到 Windows :S

Chili555的解決方案工作完美，請參閱其他線程。謝謝！

我在 L13 Yoga thinkpad 上使用 Ubuntu 19.10 時可能也遇到同樣的問題。透過恢復到較舊的核心解決了這個問題，在我的例子中，5.3.0-18 可以工作，但任何晚於該版本的核心都不起作用。

如果您最近剛安裝，您可能已經獲得了新的 18.04.4 點版本，該版本附帶新的 5.3 內核，並且可能存在相同的問題。

跑步

uname -a

它應該告訴你你有哪個內核，如果它比 5.3.0-18 新，你可能有和我一樣的問題。

您可以使用 apt 或 synaptic 套件管理器安裝 5.3.0-18。
