我已经阅读了关于此问题的许多其他帖子，并尝试了许多方法，但问题仍然存在。
我从 14.04 升级到了 16.04 - 问题就是从那时开始的。我的无线连接完美无缺 - speedtest.net 显示下载速度高达 65 Mbps。过了一会儿（大约 10 - 20 分钟 - 取决于使用情况），当我意识到我的互联网连接已经恶化时 - 相同的速度检查返回的速度低至 0.5 Mbps。如果我继续，它会在某个时候完全失败，因为 wifi 会断开连接，然后不断尝试重新连接，但没有成功。
如果我运行这些命令
sudo modprobe -r rt2800pci
sudo modprobe -v rt2800pci
连接再次完美。再过 10 或 20 分钟，然后再次发生同样的情况，直到我再次重置它。
如果您能提出任何关于导致这种情况的原因的想法，或者我该如何着手使“修复”永久化，我将不胜感激。
我的“无线信息”返回以下内容

谢谢
...我想再次将其置顶
答案1
最后，经过一个多星期的挫折后，我想我已经找到了解决这个问题的方法——如果还有其他人想拔掉自己的头发，那就不要这样做。
似乎解决这个具体问题——与棘手的问题密切相关——
rt2x00queue_flush_queue: Warning - Queue 2 failed to flush
/var/log/syslog 中的错误需要采取以下措施
运行以下命令
iwconfig
并获取接入点的 MAC 地址。我将其输入到 Wi-Fi 选项卡上的网络设置屏幕上的 BSSID 字段中
希望这对其他人有帮助！！
=========================================================================
一小时后，我注意到网速再次下降到 1 - 3 Mbps......并从 /var/log/syslog 中注意到它与 IRQ16 问题同时发生。
因此我按照建议将“irqpoll”添加到启动选项中。
要在 Ubuntu 16.04 中添加它 - 需要编辑文件/etc/默认/grub 编辑/添加一行以包含以下内容
GRUB_CMDLINE_LINUX_DEFAULT="irqpoll"
如果你已经有了值 - 只需将其添加到末尾即可
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash irqpoll"
要更新 grub cfg - 运行以下命令
sudo update-grub
你可以通过以下方式检查 irqpoll 是否已添加到你的 cfg 文件中：
cat /boot/grub/grub.cfg | grep irqpoll
您应该能够发现一些条目。
重启后，我的机器完好无损，运行 24 小时后仍然如此！
