Ubuntu18.04- iwlwifi失败

Question

无线网络突然在我的电脑上变得不可用了。我不明白为什么，我也不知道怎么激活它。任何帮助都将不胜感激。

下面是一些可能有用的日志来理解这个问题

dmesg | grep iwl

sudo modprobe iwlwifi

我建议你安装较新的固件，看看它是否有用。使用可工作的internet连接，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

重新启动并向我们展示：

dmesg | grep iwl
