我在运行 Natty 的新 Thinkpad W520 上的 Wifi 不断掉线并重新打开。下面 dmesg 的输出。有什么建议吗？

我在使用 Maverick 时遇到了这个问题，所以我安装了这个软件包linux-backports-modules-wireless-maverick-generic，并得到了一个非常稳定的系统。（此软件包提供了比默认内核更新的无线内核模块。）
对于 Natty 来说没有包linux-backports-modules-wireless-natty-generic。- 但您可以尝试安装linux-backports-modules-cw-2.6.39-natty-generic，也许您的断开连接就会消失。:)
