在被迫使用 Windows 大约一年后，我最近安装了 Ubuntu 15.04。不幸的是，自从换了系统后，我的笔记本电脑出现了一些相当严重的 wifi 问题。我怀疑这是某种驱动程序问题，但我肯定不是这类问题的专家。
我能够正常连接网络，但是我的速度只有 Windows 上的 1/3 到 1/2，并且连接存在大量抖动和数据包丢失问题。例如，我无法使用任何视频流类型的应用程序，因为它会从播放高清视频毫无问题突然变成在 SD 上每 5 秒缓冲一次。
我已将“wireless_script”的输出包含在内，该脚本似乎在这里很受欢迎。任何帮助都将不胜感激！这让我抓狂
编辑：脚本输出对于这篇文章来说太大，这是文件

答案1
首先，检查路由器中的设置。首选 WPA2-AES；而不是任何 WPA 和 WPA2 混合模式，当然也不是 TKIP。我使用固定通道（1、6 或 11）比自动通道选择更幸运。另外，确保路由器未设置为仅使用 N 速度；首选自动 B、G 和 N。进行这些更改后，重新启动路由器。
接下来，我在网络管理器中将 IPv6 设置为忽略：http://docs.fedoraproject.org/en-US/Fedora/18/html/Installation_Guide/images/netconfig/network-connections-ipv6-ignore.png 此示例适用于以太网，但您想要无线。
如果这些更改无效，我将编辑我的答案以添加其他步骤。
