最近我买了一台笔记本电脑 Acer E15 E5-553G-T4TJ，我运行的是 Ubuntu 20.04。

这台笔记本电脑配备了高通 Atheros QCA9377 作为无线网卡，我多次遇到 ping 尖峰甚至断开连接。

在常规使用中，如 YouTube、Google Meet 等，我感觉不到这个问题，但它确实存在。当我尝试玩任何游戏（又名 Lutris 下的英雄联盟）时，我真的有这种感觉。播放时我的 ping 超过 100 毫秒。

首先，我尝试购买一个新的路由器，但它不起作用。所以我决定在终端检查我的延迟，ping Google.com。令我惊讶的是，我发现了高 ping 峰值。对此很感兴趣，我尝试 ping 我的路由器，瞧，我也有我的 ping 尖峰。

这是我到路由器的 ping 日志：

话虽如此，我确信问题不在于我的路由器或 ISP，而在于我的 PC，可能与驱动程序有关。

所以我研究了很多发现什么，我发现高通创锐讯无线卡确实有问题。我找到了很多可能的解决方案，并且我已经尝试了很多。我会尝试链接到我尝试过的任何内容，但我不记得所有内容。

我试过了：

我想这就是我所做的一切，但我不确定。

我注意到当我对 GPU 施加压力时，我的 ping 会出现峰值，所以这可能是相关的。

这是我的日志：

升级到 19.10 后，我开始遇到奇怪的 Wi-Fi 行为。我的公寓里有两个同名的网络——一个强一个弱。

Ubuntu 显然应该连接到更强大的那个，而且它曾经如此。但是自从升级它总是选择较弱的，当我手动选择强的时，它会重新连接到较弱的。大约 10 分钟后，系统最终“放弃”并停留在更强的网络上。

奇怪的是，当我在我的 Wi-Fi 弹出窗口中看到两个 Wi-Fi 时，一旦我打开设置，只显示一个：

WiFi 弹出窗口 无线网络设置

有谁知道如何解决这个问题并告诉 Ubuntu 只连接到更强的 Wi-Fi？或者这是我应该报告的错误？

几天前突然WiFi适配器停止工作。

设置 UI 显示“未找到 Wi-Fi 适配器”

可能与最新的 Ubuntu 软件更新有关吗？还是旧硬件可能崩溃？如何解决这样的问题？

我已经在我的 PC 上安装了全新的 Ubuntu，但我无法让它连接到 wifi。我无法访问以太网，尝试使用网络管理器 GUI 进行连接会导致超时，并显示“网络连接激活失败”。它在装有 Windows 10 的同一台机器上运行得非常好。

Ubuntu版本是18.04，卡是高通Atheros，我卡的驱动是ath9k。

我不认为这是驱动程序问题，因为所有驱动程序检查都很好。我认为这可能与连接的持久性有关。尝试连接时，dmesg 给出以下结果：

wlp4s0: authenticate with [MAC address]
wlp4s0: send auth to [MAC address] (try 1/3)
wlp4s0: send auth to [MAC address] (try 2/3)
wlp4s0: send auth to [MAC address] (try 3/3)
wlp4s0: authentication with [MAC address] timed out

结果iwconfig：

wlp4s0    IEEE 802.11  ESSID: [Network Name]
           Mode:Managed  Access Point: Not-Associated  Tx-Power=19 dBm

“接入点”应该不是“未关联”吗？如果是这样，我该如何更改？

此外，运行iwlist scan一半时间会导致No scan results，但经过几次尝试后，它会返回相关信息。

我完全不知道该怎么做。

我正在尝试安装Atheros CSI 工具（在此处提供安装说明），在带有 QCA9377 无线适配器的戴尔 Inspiron 5570 笔记本电脑上运行 Ubuntu 18.04.2 LTS。

我能够成功完成安装说明中“编译内核”的“准备”部分中列出的所有操作。（在说明中没有指定一些我能够弄清楚的事情，比如安装make和gcc。）但是，我对这make menuconfig一步及以后的事情感到困惑。当我输入make menuconfigAtheros-CSI-Tool 文件夹时，我立即按“保存”，保存一个名为 的文件.config，然后“退出”菜单。

当我输入make -j16（我有 8 个 CPU 内核）时，输出如下：

  CHK     include/config/kernel.release

当我然后键入make modules时，这是输出：

我尝试通过从档案中安装旧版本的 Ubuntu (14.04) 来修复遇到的这些错误，但是 Wi-Fi 在该操作系统下的笔记本电脑上不起作用（这很重要，因为我正在收集有关 Wi-Fi 连接的数据使用我尝试安装的工具）。我还从在线存档中安装了旧的 Linux 内核（4.1.10），但遇到了与上图相同的错误。

我在装有 Qualcomm Atheros QCA9377 802.11ac 无线网络适配器的戴尔笔记本电脑上遇到 Wi-Fi 问题。每 5-10 分钟某处的 WiFi 就会停止接收和发送数据。我也无法连接到路由器（192.168.1.1）。如果我只是重新连接到热点，那么接下来的 5 分钟 Wi-Fi 可以正常工作。

有没有人对如何解决这个烦人的问题有任何想法？

每次我的笔记本电脑进入睡眠状态（电池电量不足）时，无线适配器都会崩溃。这使得系统完全无法使用。我无法删除驱动程序、将其终止或重新启动 NetworkManager。我也无法重新启动。

我的 wifi 似乎工作正常，但如果是我的笔记本电脑，有时它会停止工作，但同时在我的手机中，我可以看到互联网工作正常。

我的网络信息：

同样通过很少的研究，我知道我们可以在发生某些事情时看到消息dmesg，如果我错了，请纠正我。

所以在分析了这个输出之后，我注意到了这一点：
