随机“通过本地选择取消身份验证（原因：3 = DEAUTH_LEAVING）”

我在跑

uname -r
4.10.6-1-ARCH

在我的Dell XPS 13开发人员版（2014年）中。我目前在wifi上遇到奇怪的问题（我将Networkamanger nm-applet用于KDE）：

1）在最肤浅的层面上，我观察到有时它可以很好地工作：当我启动我的电脑时，它已经连接到了wifi，有时它无法以任何方式连接（wifi 总是一样）；

2）我尝试重新启动NM ：，问题仍然存在。3）有时，如果我重新启动笔记本电脑，它又可以工作了，有时却不能。

4）我尝试使用 nmcli

nmcli connection up My-WiFi 

然后我观察

总是有相同的错误。我不知道如何解决。请注意以下几点：

1）我的电脑特别是Linux（与ubuntu一起出售）

lspci -k

    Subsystem: Intel Corporation Dual Band Wireless-AC 7260

2）所有必要的服务均处于活动状态

3）如果使用USB有线eth屏蔽，则可以毫无问题地与NM连接；

4）我也尝试直接与进行连接wpa_supplicant，但是由于身份验证错误而无法连接，但是我强调我的userid和pwd是正确的，因为有时我可以毫无问题地进行连接

我该怎么办？

我看到您同时在运行NetworkManager和wpa_supplicant。我的带有Intel 9560-ac wifi卡的笔记本电脑（Inspiron 7590）遇到了类似的问题。用NetworkManager替换wpa_supplicant后，问题解决了。在此之前，我尝试了互联网上的每条建议，但都没有成功。

编辑：问题是多个dhcpcd客户端。系统现在也可以通过wpa_supplicant稳定。
