我的 WiFi 每隔几分钟或几秒钟就会被取消认证（原因：7）

我的新 Thinkpad W520 上的 Wifi 运行 Natty，经常断线然后重新打开。下面是 dmesg 的输出。有什么建议吗？

答案1

我在使用 Maverick 时遇到了这个问题，所以我安装了该软件包linux-backports-modules-wireless-maverick-generic，然后得到了一个非常稳定的系统。（该软件包提供了比默认内核更新的无线内核模块。）

对于 Natty，没有软件包linux-backports-modules-wireless-natty-generic。 - 但你可以尝试安装linux-backports-modules-cw-2.6.39-natty-generic，也许你的断开连接就会消失。:)

答案2

这是与驱动程序相关的问题，请发布结果"iw reg get"并"iw phy phy0 info"

答案3

我设法通过从 Realtek 网站下载驱动程序并从源代码编译来解决这个问题 -http://www.realtek.com/downloads/- 并在左侧字段中搜索我的无线网卡。

总结一下：解决这个问题需要两个步骤：

  1. 安装 WICD。
  2. 从源代码编译原始驱动程序。

答案4

我也遇到过这个问题。通过安装 WICD 解决了这个问题。然后卸载网络管理器。然后将 WICD 添加到启动应用程序中。然后重新启动（必不可少）。对于我来说，在许多安装中，这已经部分解决了问题
