答案1

您可能遇到了與內核模組的衝突acer-wmi。

rfkill list all說它是“宏基無線：軟阻止：是”

嘗試以下操作：

sudo modprobe -r acer-wmi
cd /etc/modprobe.d
sudo nano blacklist.conf

然後blacklist acer-wmi在文件末尾新增一行。

儲存並重新啟動。

再次重新運作rfkill list all- 如果仍存在“硬塊”，則您已透過開關或 Fn 鍵類型無線開/關停用了 wifi。

在某些筆記型電腦上，硬體開關可能非常小，很難找到 - 請查看筆記型電腦手冊。

答案2

sudo modprobe -r acer-wmi
cd /etc/modprobe.d
sudo nano blacklist.conf

然後blacklist acer-wmi在文件末尾新增一行。

完成上述操作後。

rfkill list all

    0: ideapad_wlan: Wireless LAN
        Soft blocked: no
        Hard blocked: no
    1: ideapad_bluetooth: Bluetooth
        Soft blocked: no
        Hard blocked: no

        Soft blocked: no
        Hard blocked: yes
    5: hci0: Bluetooth

        Hard blocked: no

但我無法啟用無線。網路連線下拉選單中的啟用無線文字已停用。

即使開關打開，實體硬塊仍然被停用。這是bios的問題。

您需要將BIOS設定重設為預設值。

重新啟動時按 F2 按 F9 重設 按 F10 儲存重設設定。

這對我有用。感謝@fossfreedom 和其他人。聯想ideapad Z570無線問題已修復
