CLOSE到路由器时无法连接wifi
我有一台运行ubuntu 16.04的Elitebook 8570w和一台ac3200路由器。 现在我有这个设置最特殊的问题：当我靠近路由器时我无法连接它，但是当我走得更远时，我可以连接。 当它断开连接时，它要求我重新validation自己（再次填写密码）。 实验表明，当我在路由器的-6米范围内时，我无法连接。 当我将路由器移动到另一个位置时（这也不是干扰），这似乎也会发生。 我也切换了路由器通道，也没有解决问题（尝试通道1-4-8-11）。

任何人都知道什么可能导致我的笔记本电脑在靠近路由器时无法连接？
哦，在我忘记之前，问题不会发生在Windows（决斗启动）。
我已经研究了几个使用iwlwifi驱动程序的情况，当SSID被更改为消除名称中的空格时，连接问题得到了帮助。 我建议您将网络名称从GLADOS MAINFRAME更改为GladosMainframe或GLADOS_MAINFRAME或其他类似名称。
同样，您可能会尝试改善连接性。
首先，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然后暂时设置它：
sudo iw reg set IS
当然，如果不是冰岛，请替换您的国家代码。 永久设置：
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。
接下来，我在网络管理器中将IPv6设置为忽略： http ： //docs.fedoraproject.org/en-US/Fedora/18/html/Installation_Guide/images/netconfig/network-connections-ipv6-ignore.png此示例用于以太网，但你想要无线。
如果这些更改无效，请尝试：
sudo modprobe -r iwlwifi sudo modprobe iwlwifi 11n_disable=8
如果有帮助，请将其永久化：
sudo -i echo "options iwlwifi 11n_disable=8" >> /etc/modprobe.d/iwlwifi.conf exit
