Ubuntu 16.04 - Wifi 每隔几分钟就会断线

我的 wifi 每隔几分钟就会断线一次 - 我必须断开连接并重新连接（偶尔关闭/打开路由器）。它在 Windows 和移动设备上运行良好。

电源管理已关闭，IPv6 方法设置为忽略也没有帮助。当我转到连接信息并查看速度时，如果可以正常工作，则显示 72 Mb/s，而当连接断开时，它会在 72 Mb/s、1 Mb/s 和未知之间闪烁。

我对 ubuntu 和编程还很陌生，但这里有一些输出：

任何帮助都将非常感激。

答案1

问题解决了 - 我将路由器从 O2 Box 换成了 TK-Link，现在可以正常工作了。将 wifi 标准直接设置为 802.11 b 也部分奏效，但速度非常慢，我对这个解决方案并不满意。

对我来说不起作用但对其他人来说可能是解决方案的方法：
