Ubuntu 16.04(Qualcomm Atheros)中的 Wi-Fi 非常慢

Ubuntu 16.04(Qualcomm Atheros)中的 Wi-Fi 非常慢

我有 Acer Aspire E 15,我的 Wifi 可以运行,但是速度很慢(有时我无法发送电子邮件)。

我尝试过互联网上的一些解决方案,但都没有效果。

lspci 的结果:

02:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:0042]    (rev 30)
Subsystem: Lite-On Communications Inc Device [11ad:0806]
Kernel driver in use: ath10k_pci

我收到以下消息:

不幸的是,使用反向移植的解决方案不起作用:(

不幸的是,我不明白上述消息中的内容。您能提示我如何解决这个问题吗?

我从 2004 年开始使用 Ubuntu,可以解决一些小问题,但我从来没有遇到过 WiFi 问题 :(
