我的WiFi每隔几分钟或几秒就会被取消认证（原因：7）
我在运行Natty的新Thinkpad W520上的Wifi不断退出并重新开始。 从下面的dmesg输出。 任何建议？

对于Natty，没有包linux-backports-modules-wireless-natty-generic 。 – 但你可以尝试安装linux-backports-modules-cw-2.6.39-natty-generic ，也许你的断开连接会消失。 🙂
这是与驾驶员有关的问题，请发布"iw reg get"和"iw phy phy0 info"
我设法通过从Realtek网站下载后从源代码编译驱动程序来解决这个问题 – http://www.realtek.com/downloads/ – 并在左侧的字段中搜索我的无线网卡。
因此，总结一下：修复这个步骤需要两个步骤：
- 安装WICD。
- 从源代码编译原始驱动程序。
我也有这个问题。 它是通过安装WICD解决的。 然后卸载网络管理器。 然后将WICD添加到启动应用程序中。 然后重启（必不可少）。 对于我来说，在许多安装中，这部分地解决了这个问题
