我的 ubuntu 中的 wifi 管理器似乎有点问题。
通常，当连接断开时，我必须等待 10 分钟才能恢复，甚至必须重新启动（但效果并不总是有改善）；
我的手机可以轻松连接，但电脑却无法识别我的连接
有时连接时不会在连接图标中显示，或者它决定不显示有关它的任何详细信息
没有连接诊断工具作为功能
如果它愿意连接，他会考虑 5 分钟，然后放弃，然后，如果他觉得慷慨，它就会连接到我的 wifi。
我该如何改进 wifi 管理器或者找到替代方案？
我看到了类似的问题（关于替代管理器），但我指出了这 5 个具体问题，并且我对这个操作系统相当了解，希望得到您的意见。

答案1
首先，检查路由器中的设置。最好使用 WPA2-AES；不要使用任何 WPA 和 WPA2 混合模式，并且肯定不是TKIP。其次，如果您的路由器支持 N 速度，那么在 2.4 GHz 频段使用 20 MHz 的信道宽度（而不是自动 20/40 MHz）可能会获得更好的连接性，尽管这可能会影响 N 速度。使用固定信道（1、6 或 11）比自动信道选择更能带来好运。此外，请确保路由器未设置为仅使用 N 速度；自动 B、G 和 N 是首选。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。
