Wifi 卡不工作、rfkill 硬阻塞、modprobe 不工作、重新安裝舊版驅動程序、重新啟動等

  • March 14, 2020

這是我的第一篇文章，所以請告訴我關於我發帖的位置、格式或其他任何內容是否需要更正

簡而言之，我的 wifi 卡，Intel Centrino Wireless-N 2200，如 所述lshw -class netowkr，已經停止工作，老實說，我不知道如何修復它。我提供了幾個命令的輸出，這些命令可能有助於解決此問題，所以如果需要任何其他資訊，請告訴我。

這是在 Thinkpad x230 上，按 Fn + F5 切換 wifi 無效。我看到有人提到在 Fedora 上打開飛行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。該問題存在於所有核心版本中

  • sudo rmmod iwldvm，然後是sudo modprobe iwldvm. 在此之後，rfkill 顯示它沒有被硬阻止，但是任何啟用 wifi 的嘗試都失敗

  • 使用 GUI 啟用 wifi

  • 在 BIOS 中禁用 wlan，然後重新啟用 - 在 BIOS 中啟用

所有與無線相關的設置。

如果啟用了藍牙和wwan ，則 Wifi 工作似乎沒有關聯 - 遵循此連結，安裝相關驅動程序，並cp iwlwifi-2000-6.ucode /lib/firmware按照驅動程序隨附的 README 中所述執行

這是我在系統設置中列出的規格

重新啟動後， rfkill 被重置為hard block: yes

即使一直啟用無線硬體開關，打開和關閉它幾次也解決了這個問題
