Intel Wireless 7260卡有时无法连接到WiFi
（也发布在Reddit ）
我有一个奇怪的问题。 我的机器有时（通常不是肯定的）没有连接到我的家庭wifi。 我可以轻松连接到Android设备热点。 Windows机器也连接。 最后，我可以使用我的Android设备作为USB wifi卡。 我知道我应该在这里提供一些数据，我不知道我应该提供哪些技术数据，但这里有一些奇闻轶事：
- 目前，我的家庭网络没有密码或名称中的空格。
- 根据我的经验，如果我等待足够长的时间（比如一个小时），那么连接的可能性会更高。
- 这可能是巧合，但通常，在我将手机作为WiFi卡插入后，机器会立即连接。
- 我有两台联想机器（Edge 13和ideapad u330p）都没有连接。 Edge机器目前运行Arch，但Ubuntu也没有连接它。 有趣的是，Lubuntu的现场USB连接在边缘机器上。
我更关心ideapad机器，因为边缘机器很快将变成通过电缆连接的固定机器。 那么，我该如何避免/处理这一不幸事件呢？
我尝试过的事情：
- 更新英特尔固件 – 它仍然无法连接。 我注意到要停止
iwlwifi我必须停止iwlmvm和iwldvm。
这是链接脚本的输出。 我现在在校园里，所以事情看起来可能不像我描述的那样。 根据我的理解，问题出在网卡（intel 7260）上，它有新的固件可用，但我还是没有找到它来激活它。

在我的英特尔无线网卡无线问题后，我研究了一下，发现了一些常见的尝试来修复它。 我自己做了这些，并且在我的笔记本电脑上有更好的稳定性。
我不记得我所遵循的确切网站，但快速谷歌搜索慢慢记住我的记忆，这些是我做的两件事（来自http://itsfoss.com/speed-up-slow-wifi-connection-ubuntu/ ）
1）禁用802.11n
sudo rmmod iwlwifi sudo modprobe iwlwifi 11n_disable=1
这将在下次重启之前进行更改。 测试它，看看你是否有一个更稳定的无线AP连接。 如果是这样，您可以通过执行以下操作使其永久化（您始终可以通过编辑该文件并删除它添加的行来恢复此更改）
sudo su echo "options iwlwifi 11n_disable=1" >> /etc/modprobe.d/iwlwifi.conf
2）禁用无线网卡电源function
sudo iwconfig
它会为您提供无线设备的名称。 通常它应该是wlan0。 现在使用以下命令：
sudo iwconfig wlan0 power off
我遇到了与我的英特尔3160ac类似的问题。 使用wavemon我发现重试次数很多，这可能是导致频繁断线的原因。 请关注tgm4883所说的内容，但添加：
$echo "options iwlmvm power_scheme=1" | sudo tee /etc/modprobe.d/iwlmvm.conf
$echo "options iwlwifi bt_coex_active=N swcrypto=1 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
$sudo reboot
如果问题没有解决，我建议看看这个错误报告： https ： //bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1354975
基本上安装内核3.13.0-37_3.13.0-37.64 + iwlltr0001来自： http ：//people.canonical.com/~sforshee/iwl-ltr/trusty/
并安装linux-firmware 1.127.7。
然后，如果它不起作用，您可以再次尝试我上面写的命令。
