Ubuntu 20.04 中无法使用 Wi-Fi

我的笔记本电脑是联想 Legion Y530（i7 8th - 16GB 内存 - GTX1050）。我为它运行的是 Ubuntu 20.04，但 Wi-Fi 出现了问题。当我打开 Ubuntu 时，Wi-Fi 找不到任何调制解调器。

我试过：

lspci -knn | grep Net -A3; rfkill list

输出：

    Soft blocked: yes
    Hard blocked: no

的输出sudo lshw -C network为：

试试这个，我有一台联想 530s，带 rtl8822be，它对我来说很管用。你应该是 root 用户。

安装后记得运行命令sudo apt-get update。

有时您应该安装两次。

第一次安装后，如果不成功，请运行命令./make clean并再次安装。
