当它掉下来的时候，它的末端syslog看起来是这样的：

有时我可以通过打开和关闭 Wi-Fi 来重新启动它，有时将其置于飞行模式来重新启动它，但是，大多数时候当我尝试修复它时，它会锁定整个系统。
我已经从 git repo 安装了最新的 ath10K 驱动程序（bin-2），但这没有帮助。
有什么想法可以对此进行排序吗？
更多信息。这似乎是某种超时。有趣的是，如果我在 wifi 上传输某些内容，它似乎不会掉线。只有当 wifi 上没有实际活动时它才会关闭（ping 似乎不足以使其保持活动状态）。
还有更多信息... 这不会发生在 Fedora 31 live CD 上。嗯...
答案1
就在我准备放弃 Ubuntu 并安装 Fedora 时，我遇到了这个解决方案。
解决方案似乎是按照这里的说明进行操作......
适用于 Ubuntu 系统的 Killer N1535 无线固件手动更新指南
按照这些说明进行操作，现在，除了睡眠后图标上显示一个“？”之外......wifi 似乎保持连接状态。
