答案1

首先,检查此修复是否适合您。终端:

sudo modprobe -r ideapad_laptop

如果这能修复 WIFI,对我来说确实如此。将其永久化。终端:

sudo nano /etc/modprobe.d/blacklist.conf

在文件底部添加以下行:

# Fix for WIFI hard block
blacklist ideapad_laptop

答案2

我会在终端运行这个

echo "blacklist ideapad_laptop" | sudo tee /etc/modprobe.d/ideapad.conf

重启并查看 wifi 是否可用

然后,如果 wifi 工作正常,则发布结果,以防sudo dmidecode | grep -i version内核开发人员看到此信息
