英特尔迅驰 Wireless-N 1000 再次问世！Ubuntu 13.04 x64

首先，我必须说，我尝试了关于这个概念的所有文章。问题是它以 3 种主要形式随机停止工作：

  1. 有时它会断开无线网络并自动重新连接
  2. 有时会断开连接，无论如何都无法连接（需要重新启动）
  3. 有时它仍处于连接状态，但无法 ping 或浏览或执行其他操作。

我已经尝试使用以下命令禁用 N mod：

sudo modprobe -r iwlwifi
modprobe iwlwifi 11n_disable=1 (or 0, whatever)

它没有帮助。这些是断开连接并且直到重新启动才连接时的lspci结果：sudo lshw -C networkifconfigiwconfigrfkill list

答案1

自从 12.04 LTS 以来，我就遇到了同样的问题，这真是太烦人了。首先，我要说的是，截至今天，一切似乎都运行正常，说明适用于，13.10但我怀疑解决方案与兼容13.04；如果问题仍然存在，我将相应地编辑我的答案。

我今天升级到了 13.10，希望这个问题已经得到解决，但再次令人失望。经过一番研究官方/社区文档并阅读一些不相关但相关的问题[2]，[3]，[4]， 和[5]我冒险尝试了下一个看似合乎逻辑的路径：检查 Ubuntu 是否使用英特尔提供的驱动程序和固件。快速查看后发现，没有/lib/firmware特定的固件！Intel® Centrino® Wireless-N 1000

您可以找到设备硬件的固件下载这里并附有安装说明这里。就你的情况而言，我下载了固件为Intel® Centrino® Wireless-N 1000。注意：提供的链接适用于内核版本 3.2+。如果我没记错的话，它应该适用于 13.04，但为了确保万无一失，请运行以下命令：uname -a. 下载固件后，按照说明执行以下操作：

$ tar -xvzf iwlwifi-1000-ucode-39.31.5.1.tgz 
$ cd iwlwifi-1000-ucode-39.31.5.1/
$ sudo cp iwlwifi-1000-5.ucode /lib/firmware/

就是这样！正如我所说，这已经奏效了迄今为止如果问题再次出现，我会修改或删除这个答案，但对于我和所有遇到这个问题的人来说，我希望这是一个永久的解决方案。
