我在桌面上安装了全新的 ubuntu技嘉无线网卡插入它。默认的 ubuntu 驱动程序似乎适用于它，这很好，因为我找不到专有的 Gigabyte linux 驱动程序。但是，速度非常随机，并且通常会下降到 ~.2mbps 范围，直到我禁用然后启用 wifi。
我发现了很多与此类似的答案，但由于 wifi 问题范围很大，我一直在避免涉及例如删除模块等的答案。我可以开始调查什么来找到特定于我的机器/构建的此问题的根源，然后解决它？

答案1
我拥有并成功使用了两台英特尔无线设备。几年来，我在数千篇论坛帖子中磨练了一些技巧。
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。其次，如果您的路由器支持 N 速度，那么使用 2.4 GHz 频段的 20 MHz 信道宽度（而不是自动 20/40 MHz）可能会获得更好的连接性，尽管它可能会影响 N 速度。我也更喜欢使用固定信道（1、6 或 11），而不是自动信道选择。此外，请确保路由器未设置为仅使用 N 速度；首选自动 B、G 和 N。
我注意到您的 SSID 名为“Speedy Remember Harambe”。我最近处理了一个案例，通过删除名称中的空格，连接性得到了显著改善。我建议您尝试将网络重命名为 SpeedyRememberHarambe 之类的名称。
完成这些更改后，重新启动路由器。
接下来，我建议明确设置你的监管范围。检查你的：
sudo iw reg get
如果您选择 00，则这是一个通用的设置。请在此处查找您的设置：http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2然后暂时设置一下：
sudo iw reg set IS
当然，如果不是冰岛，请替换您的国家代码。永久设置它：
gksudo gedit /etc/default/crda
如果您没有文本编辑器 gedit，请使用 nano 或 Kate 或 leafpad。
将最后一行改为：
REGDOMAIN=IS
仔细校对，保存并关闭文本编辑器。
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。
重新启动计算机并让我们听取您的报告。
