我的 wifi 管理器出现严重问题,如何解决?有其他解决方案吗?

我的 wifi 管理器出现严重问题,如何解决?有其他解决方案吗?

我的 ubuntu 中的 wifi 管理器似乎有点问题。

  1. 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);

  2. 我的手机可以轻松连接,但电脑却无法识别我的连接

  3. 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

  4. 没有连接诊断工具作为功能

  5. 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。
