我在二手 HP Z420 工作站上執行 Fedora 32。當我使用乙太網路連線時，我的網路連線工作一切正常，但當我搬到沒有乙太網路輸出並必須使用 Wi-Fi 的公寓後，我無法在電腦上獲得 Wi-Fi 連線上班。
問題不在於 Wi-Fi 連線本身，因為我用於遠端工作的 Windows 10 筆記型電腦能夠連接到 Wi-Fi 一切正常。
我使用的是插入電腦 USB 連接埠的 TP-Link TL-WN823N USB Wi-Fi 轉接器。當我運行 lsusb 時，它將適配器顯示為：
Bus 001 Device 003: ID 2357:0109 TP-Link TL-WN823N v2/v3 [Realtek RTL8192EU]
當我啟動電腦並登入 Fedora 時，系統能夠找到當我單擊工作列上的網路圖示時顯示的 Wi-Fi 網路名稱，以及其他幾個 Wi-Fi 網路（屬於給其他我不知道密碼的人） 。當我單擊網路名稱時，Fedora 要求我輸入網路密碼。當我輸入它並單擊“連接”時，沒有任何反應。我無法連接，甚至沒有收到有關密碼錯誤或其他任何資訊。
這是我運行 dmesg 時出現的內容：

我讀過這篇 SuperUser StackExchange 貼文：https://superuser.com/questions/911635/wifi-authentication-times-out並嘗試了解決方案。它不起作用。 Fedora 似乎忽略了「wd_disable」參數。它還忽略了另一個參數“bt_coex_acrive”（是的，它實際上在 dmesg 輸出中拼寫為“acrive”，而不是“active”），我不知道它來自哪裡。它不會出現在 /etc/modprobe.d 目錄中的任何檔案中。
我之所以能夠在 StackExchange 上發表這篇文章，是因為我目前在公司辦公室工作，那裡有可用的 Internet 連線。
有誰知道是什麼原因造成的以及我該如何解決它？如果需要，我可以提供更多詳細信息，但存在延遲，因為我必須在家庭計算機（以診斷問題）和工作計算機（以將其報告給 StackExchange）之間切換。
如果解決方案涉及使用 dnf 安裝更多軟體，那麼我不知道如何才能使用 dnf，我首先需要網路連線。
2021 年 11 月 6 日更新：我已經安裝了此處找到的 rtl8192eu 核心模組：https://github.com/Mange/rtl8192eu-linux-driver 那沒有幫助。沒有改變。 Wi-Fi 轉接器可辨識網絡，但無法連接到該網路。
這是我在 dmesg 輸出中發現的內容：
