15.10瑜伽13（第一代）Realtek nic的网络速度慢
我的下载和上传速度分别低至0.5 mbps和1 mbps。 他们应该在43mI左右刚刚安装了15.10的第一代瑜伽13。
我尝试过从这篇文章中交换驱动程序和步骤： http ： //itsfoss.com/speed-up-slow-wifi-connection-ubuntu/
没有成功。
在对此进行故障排除时，将不胜感激。
网卡是Realtec rtl8723au：

我遇到问题的驱动程序是Larry Finger提供的此无线卡的原始驱动程序（并添加到Linux内核中）。 当前的驱动程序维护人员Jes Sorensen表示，驱动程序可能无法正确启动芯片/可能无法完全了解正确的电源顺序。
目前的维护者说你可以尝试他的新驱动程序rtl8xxxu。 它还不是我发现的linux版本的一部分，但如果你想编译它并尝试一下，他给了我一个他的Kernel fork的链接： http ： //git.kernel.org/cgit/linux /kernel/git/jes/linux.git/log/?h=rtl8723au-mac80211 （您可以在日志中看到他在2015年10月14日添加了rtl8xxxu）它应该是即将发布的版本之一。
我懒得编译一个内核，而我只是在网络速度下降时才进行电源循环。
