Wifi连接无法与英特尔NUC +无线AC 7620配合使用
我在这里发帖，希望通过Ubuntu 15.04上的无线AC 7620解决我在英特尔NUC上的wifi连接问题。
我已经复制了无线信息脚本的输出下面，但在我有一些关于我遇到的问题的简短历史和描述之前。
我大约一年前建立了我的NUC，并在媒体中心使用后直接安装了Ubuntu 14.04。 一切都很完美，快速稳定的WiFi连接。 当Ubuntu 14.10发布时，我没有升级（我想继续使用LTS版本），但一直在进行定期更新。
然后有一天到另一天（我想说的是2014年10月/ 11月左右），一切都出错了：连接到wifi定期丢失，有时每隔几分钟，传输速率下降到如此低，显示需要几分钟谷歌主页，连接将丢失，永远不会回来。
我经历了几个论坛/网站/维基并尝试了很多东西。 我认为最好的结果是使用iwconfig禁用电源管理。 有时也禁用/重新启用wifi和/或网络。 升级到更新的Ubuntu版本有时会改善这种情况，有时候不会。
今天，我回到家里想再次使用我的NUC，情况比以往更糟。 以下是症状：
- NUC在启动时快速连接到我的wifi网络。
- 信号强度很好，我想说大约75％。
- 连接稳定。
- 到任何网站是不可能的。 例如，如果我尝试访问Google主页，Firefox滚轮将永久转动，但不显示任何内容。
- 尝试使用apt-get update进行更新确实会触发一些数据传输，但传输速率非常低（我在五分钟后取消它并且没有完成）。
我的路由器/互联网访问是一个Freebox v5，但我认为问题确实来自NUC / Ubuntu，因为我在wifi上运行Windows 7桌面和Debian Jessie nettop，但没有一个有这些问题。
在此先感谢您的帮助 ！
任何额外的命令行或测试，请告诉我，我会尽快完成！
注意：我从iwlist扫描中移除了所有不属于我的wifi网络，以保持低于30000个字符的限制。

接下来，检查路由器中的设置。 WPA2-AES是首选; 不是任何WPA和WPA2混合模式，当然也不是TKIP。 其次，如果您的路由器能够达到N个速度，那么您可以在2.4 GHz频段中使用20 MHz的信道宽度而不是自动20/40 MHz进行更好的连接，尽管它可能会影响N个速度。 我也有更好的运气，固定频道，1或6或11，而不是自动频道选择。 此外，请确保路由器未设置为仅使用N个速度; 自动B，G和N是优选的。 进行这些更改后，重新启动路由器。
接下来，我建议明确设置您的监管域名。 检查你的：
sudo iw reg get
如果你得到00，那就是一个大小也许适合所有的设置。 在这里找到你的： http ： //en.wikipedia.org/wiki/ISO_3166-1_alpha-2然后，永久设置它：
gksudo gedit /etc/default/crda
如果您没有文本编辑器gedit，请使用nano或kate或leafpad。 将最后一行更改为：
REGDOMAIN=IS
仔细校对，保存并关闭文本编辑器。 当然，如果不是冰岛，请替换您的国家代码。
重新启动NUC，让我们知道稳定性是否得到改善。
嗨再次感谢您的反馈，
所以这就是我所做的：
- BIOS更新：完成2015年6月12日发布。之前安装的版本大约有一年的历史。
- 路由器设置：我选择了WPA（TKIP + AES），因为在我的路由器接口中声明这是首选模式（虽然没有说明原因）。 我的其他选择是：WEP（但由于安全性低，我会忽略这一点），WPA（TKIP）或WPA（AES / CCMP）。 你特别推荐一个吗？
- 路由器通道从13更改为6。
- 独占使用路由器的N模式：该选项在接口中不存在这种或那种方式。 但是我很确定路由器不在N模式，因为我的nettop只支持B和G，但仍能连接到wifi。
- 路由器重启完成。
- iw reg get的输出确实是00。
- REGDOMAIN已从00更改为FR。
- iw reg get的输出现在是FR。
- NUC重启完成。
我昨天做了几个测试，无线响应显然更好。 我能够通过apt-get以500到700 ko / s的下载速度进行更新（我认为这是可以的）。 互联网浏览速度非常快。 今天可能稍慢，但很难说。
看起来这个问题已经解决了，但不幸的是，我过去习惯了这些临时改进。 让我们暂时考虑这个问题，如果问题出现几周/重新启动/更新后我会回复。
再次感谢 ！
我也有这个问题与英特尔nuc头骨。 驱动程序和BIOS更新没有帮助。 但是我的路由器中的频道从“自动”切换到频道“1”就完成了这项工作。
