在Centrino Advanced-N 6230 中经常从Wifi取消认证（原因：6）
几天后，我的wifi每隔几分钟就会中断。 我使用’vanilla’Ubuntu安装（即Unity，NetworkManager等）。 大约一个小时后，连接完全被切断，NetworkManager再也找不到网络了。 在NetworkManager菜单中切换“启用Wi-Fi”可以让我再次查找并连接到网络。

我想这可能是与硬件相关的问题，但据我所知，Windows上不会出现问题（8,64位）。 但是，由于重新连接速度如此之快，我到目前为止可能已经错过了它。
知道问题是什么吗？ 什么是“原因6”以及可能导致什么原因？ 如何进一步调试问题？
看起来像Trusty之后的网络问题可能是同一个问题。 如果有人可以在那里发布我的链接，我将不胜感激，因为我没有足够的声誉这样做。
我通过在/etc/modprobe.d/中的某个文件中添加’options iwlwifi 11n_disable = 1’来禁用mode-N无线。 从那以后我没有断开连接！
我有类似的问题，发现以下帮助（没有解决）我的问题：
检查您的无线设置使用的监管机构：
iw reg get
我的默认为’00’，这是未设置的。 当我在美国时，我跑了
sudo iw reg set US
我的无线设置似乎使我的设备的行为更加一致，虽然我也在运行
在文件/etc/modprobe.d/iwlwifi.conf中禁用802.11n协议
options iwlwifi 11n_disable=1
在文件/etc/sysctl.conf中我禁用了ipv6协议
net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1
最后，我的无线路由器已设置为不使用QOS / WWN
对我来说，它有助于更改自动频道以修复我的wlan路由器上的频道。
我也收到了像wlan0: deauthenticated from aa:bb:cc:dd:ee:ff这样的错误信息wlan0: deauthenticated from aa:bb:cc:dd:ee:ff一直都是我发现（使用命令wpa_cli ）这是在wlan路由器更改其频道后发生的。 因此我现在使用固定的wlan通道来解决这个问题。
您可以使用wpa_cli查看当前使用的频道。 它会在您更改频道时显示。 当wlan频道改变时，您可以看到频率与以前不同。
它不是要找到任何免费的wlan频道，但是当频道被更改时，似乎wpa_supplicant存在问题并且它不再起作用，而是它试图一直重新连接而没有成功。 在那段时间之后你会得到很多wlan0: deauthenticated from aa:bb:cc:dd:ee:ff messages（mac地址会有所不同）。 因此，解决方案是使用将wlan通道固定到您喜欢的任何通道。
