我浏览了无数的教程和类似的问题，试图解决这个问题，但我仍然无法让 wifi 正常工作，所以我决定发布一个新问题。
我双启动了 Windows 电脑和 Ubuntu 14.04，因为我的教授需要我与实验室兼容。在我的 Windows 分区上，wifi 可以使用。在 Linux 上，它根本不起作用。我尝试过 sudo-apt get install 许多 backport，但都不起作用。有一个答案在这这几乎解决了我的问题，但是我尝试执行该命令sudo cp /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin，但在完成所有其他步骤后仍找不到文件。
这个帖子非常有帮助，但是当我按照这些步骤操作时并没有解决我的问题。
以下是我从一系列命令行查询中得到的输出。我是 Linux 新手，我很迷茫。任何帮助都将不胜感激！
