在大多数情况下，我的无线网络工作非常好。但是大约每天一次，随机的时候我被断开连接，我的无线的密钥环认证弹出。所有正确的信息都在密钥环中输入，但当我单击connect时，它在重新连接网络时失败，身份验证窗口再次弹出。网络处于正常工作状态，这是唯一一台受影响的计算机。这是修复通过重新启动我的电脑，但它是一个生产机器，所以必须停止我的工作和重新启动变得相当令人沮丧。

下面是弹出的屏幕：

无线网卡是D-链路Xtreme N DWA-552。

以下是发生问题时日志的输出：

请帮帮忙！

更新: VLC似乎使这个问题更加频繁。在正常情况下，它每天只发生一次，但当我昨天运行VLC时，它在短得多的时间内坠毁了好几次。不知道这是否相关，但这很奇怪.

我也有这个问题，在我的MacBook 2,1。没有什么你可以做的，但你可以重新设置模块，至少它会再次工作。
