這是我的第一篇文章，所以請告訴我在發文位置、格式或其他方面是否有任何需要糾正的地方
簡而言之，我的 wifi 卡（Intel Centrino Wireless-N 2200）lshw -class netowkr已停止工作，老實說，我不知道如何修復它。我提供了幾個可能有助於解決此問題的命令的輸出，因此如果需要任何其他信息，請告訴我。
這是在 Thinkpad x230 上，按 Fn + F5 切換 wifi 不起作用。我看到提到在 Fedora 上開啟飛航模式是一個常見的錯誤，可能會導致破壞 wifi 功能。
我嘗試過的事情：
-sudo rfkill unblock all
重新啟動
- 從核心 5.5.6 升級到 5.5.7 和 5.5.8。該問題存在於所有內核版本中
- sudo rmmod iwldvm，其次是sudo modprobe iwldvm。此後，rfkill 顯示它沒有被硬阻止，但任何啟用 wifi 的嘗試都會失敗
- 使用 GUI 啟用 wifi
- 在 BIOS 中停用 wlan，然後重新啟用 -
在 BIOS 中啟用所有與無線相關的設定。 Wifi 工作似乎與藍牙和 wwan 是否啟用無關
-followed這個連結，安裝相關驅動程序，並cp iwlwifi-2000-6.ucode /lib/firmware按照驅動程式隨附的自述文件中的概述運行
這是系統設定中列出的我的規格

儘管無線硬體開關一直處於啟用狀態，但打開和關閉幾次就解決了問題
