Ubuntu 16.04 ACER Aspire E14 上的 Wifi 无法使用

自从 14.04 以来，我的 wifi 就一直有问题...我升级到 16.04 并尝试过，sudo apt-get update && upgrade但没有成功...我对 Linux 还很陌生，所以我无法找出问题所在。以下是一些我认为可能有用的系统信息。

lspci -knn | grep Net -A2

看来您需要固件！请在网络连接正常的情况下尝试：

sudo apt-get update
sudo apt-get install linux-firmware

重启。可以正常工作吗？如果不行，请检查：

sudo dpkg -s linux-firmware

我们希望看到安装的版本是 1.157.13。如果没有，请尝试：

cd /tmp
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.157.13_all.deb
sudo dpkg -i linux-firmware*.deb

重启。可以正常工作吗？

编辑：我怀疑下载的内容不知何故被损坏了。让我们再试一次：

cd /tmp
rm -rf linux-firmware*
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.157.13_all.deb
ls -al

我们希望大小是44364698，如果是这样，那我们就安装它吧：

sudo dpkg -i linux-firmware_1.157.13_all.deb

如果下载的包大小不同，停止并发布尺寸。

请发布任何错误或警告。
