答案1
您可能遭遇了内核模块冲突acer-wmi
。
rfkill list all
说是“acer-wireless:软阻止:是”
请尝试以下操作:
sudo modprobe -r acer-wmi
cd /etc/modprobe.d
sudo nano blacklist.conf
然后blacklist acer-wmi
在文件末尾添加新行。
保存并重新启动。
再次重新运行rfkill list all
- 如果仍然有“硬阻止”,则您已通过开关或 Fn 键类型的无线开/关禁用了 wifi。
在某些笔记本电脑上,硬件开关可能很小,很难找到 - 请查看笔记本电脑手册。
答案2
sudo modprobe -r acer-wmi
cd /etc/modprobe.d
sudo nano blacklist.conf
然后blacklist acer-wmi
在文件末尾添加新行。
完成上述操作后。
rfkill list all

但无法启用无线。网络连接下拉菜单上的 enablewireless 文本被禁用。
即使开关已打开,物理硬块仍处于禁用状态。这是 bios 的问题。

您需要将 BIOS 设置重置为默认值。
重启时按 F2 按 F9 重置 按 F10 保存重置设置。
