我正在工作站上安装 Ubuntu 14.10。
由于我没有 wifi 卡，所以我使用华为 mate 进行 USB 网络共享。手机是 Android kitkat 4.4.2
Network-Manager 正确设置了连接，奇怪的是下载速度最高可达 40KB/秒。实际上，无论是在手机上还是在 PC 上，都没有其他进程占用带宽。在 Fedora 20 上也发生了同样的事情。在 Windows 上，连接速度为 300 KB/秒，在 OSX 和手机上也是如此。

正如您所看到的，我正在安装，但是以这样的速度，它花了很长时间

答案1
免责声明：这不是使用现有设置的解决方案，但它可能会很有效
您是否尝试过使用应用程序掌上网络+? PdaNet+ 包含 PdaNet 和 FoxFi。大约一年来我都没有使用过它们，但当我出差并且仍然拥有无限数据（使用 Verizon）时，FoxFi 帮助我将手机用作热点，而无需支付任何额外的热点费用。我每月使用超过 60 GB，而带宽也不受限制。在 LTE 上，我的速度超过 25 mbps。
笔记：PdaNet+ 和 FoxFi 仅适用于 Android 手机，但我知道您已经可以使用了。此外，如果您的手机无法支持热点功能，您也可以使用 USB 网络共享功能与 PdaNet+ 连接
您可以在这里获取该应用程序：掌上网络+
答案2
好吧，我想到了一些问题，但我打算尝试一下。
当您说在 Windows 中获得了很快的速度时，是使用同一台计算机吗？
您是否启用了 UFW 等防火墙？
sudo ufw status会告诉您是否启用。如果启用了，请尝试禁用它，看看速度是否提高sudo ufw disable。
我认为真正的问题是
在您的日志中，您连接了一堆 USB 设备，而 USB 的带宽有限。我在用手机，所以在写这篇文章时看不到您的帖子，但我想我看到了几个不同的 USB 驱动器，以及一个键盘和鼠标和某种 USB 蓝牙设备。
拔掉除键盘、鼠标和电话之外的所有 USB，然后看看是否能获得更好的速度。
我想我也在某处看到过 USB 集线器，如果是这样，那么手机是连接到集线器还是 PC 上的实际 USB 端口？
