Ubuntu 18.04-iwlwifi 失败

我的电脑上的 wifi 突然不可用了。我不明白为什么，也不知道如何重新激活它。任何帮助都将不胜感激。

以下是一些可能有助于理解问题的日志
dmesg | grep iwl

我建议您安装较新的固件以查看是否有帮助。在有网络连接的情况下，打开终端并执行以下操作：

wget http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.183.2_all.deb
sudo dpkg -i linux*.deb

重新启动并显示：

dmesg | grep iwl
