问题描述
我有一个System76 Gazelle，gapz8，运行Ubuntu 14.04。我的wifi一直随机消失。我有一个新路由器，所以我不认为这是问题，但是我在公寓楼里，所以信号可能很拥挤。我的计算机仍将wifi注册为已连接，但停止发送和接收数据。我发现断开与wifi的连接并重新连接可以解决此问题，但几分钟后可能会再次发生。有谁了解这个问题或如何解决？我很乐意提供更多信息，如果可以澄清这个问题，请告诉我。

########## wireless info END ############最佳思路
在终端(CTRL + ALT + T)中一次运行以下命令：
echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwldvm
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi
这是做什么的？ 11n_disable选项禁用802.11n功能。将其添加到/etc/modprobe.d/iwlwifi.conf可使更改在重启后仍然存在(因为它将是模块配置的一部分)。 modprobe -rfv命令将删除内核模块iwldvm和iwlwifi，最后最后一行modprobe -v将iwlwifi重新添加回去。
要知道这些内核模块是做什么的，可以运行modinfo <module name> | grep description，它将告诉您以下内容：
iwlwifi是用于Linux的Intel(R)无线WiFi驱动程序(通用Intel驱动程序)
iwldvm是适用于Linux的Intel(R)无线WiFi链接AGN驱动程序(更具体的驱动程序)
其他建议
现在，检查路由器中的设置。首选WPA2-AES；没有任何WPA和WPA2混合模式，当然也没有TKIP。其次，如果您的路由器具有N速的能力，那么您可能会在2.4 GHz频段拥有20 MHz的信道宽度，而不是自动20/40 MHz的运气更好。我还可以通过固定频道1、6或11来获得更好的运气，而不是自动选择频道。进行这些更改后，您可能需要重新启动路由器。
次佳思路
更改IPv6的无线设置。我用我的笔记本电脑进行了尝试，该笔记本电脑一直在断开连接，到目前为止，整整一天，我都没有一个辍学！它似乎正在工作。在Ubuntu的右上角，单击显示连接性的无线网络图标。在底部的下拉菜单中，选择”edit connections”，然后突出显示您的无线连接名称。选择“编辑”，然后选择“ IPv6”选项卡(在“ IPv4”选项卡的右侧)并将设置从”automatic”更改为”ignore”。保存并退出。重新启动电脑。那解决了我的问题，希望您也能解决。
第三种思路
编辑无线设置，将IPv6方法设置为”ignore”。
这可能是解决此问题的非常简单的方法。通过康卡斯特(Comcast)连接时，有时甚至在酒店中，我的12.04无线连接每隔几分钟就会掉线。这在不同的Comcast无线设置中始终发生。在其他许多无线设置中，它都非常可靠(例如在我的工作场所，例如星巴克)。
经过许多复杂的修复工作后，我终于迷失了上述解决方案：没有辍学了。
