我在跑
uname -r
4.10.6-1-ARCH
在我的Dell 13开发者版(2014年)上,我的WiFi (我用NetworkManager和nm-applet
一起使用KDE)出现了奇怪的问题: :
nmcli
:nmcli连接我的-WiFi。然后我观察

连接,但由于身份验证错误,这是不可能的。然而,我强调我的用户I和密码是正确的,因为有时我可以毫无问题地连接。我该怎么办?

可能是你的WiFi芯片有问题。我在笔记本电脑和安卓手机上都有这个问题。如果你还没有的话,有一件事可能会有帮助,那就是取下笔记本电脑的后盖,然后用压缩机或罐装空气把它吹灭。有时候,灰尘足以破坏电子线路,因为它会导致建筑/短裤,有可能导致任何事情发生。我不能肯定我已经“修复”了像这样的WiFi卡,但是我可以说我从来没有弄坏过这样的卡,而且当我把所有的灰尘都从板上排出时,通常会有一个明显的速度差异。
或者,考虑到WiFi芯片制造商主要是如何支持的,您所使用的内核模块可能是错误的。我在“棱镜”设备上处理监视器模式时遇到了这个问题(尽管Linux甚至告诉我,棱镜驱动程序在监视器模式下不能很好地工作)。
最后,我情不自禁地注意到您的路由器正在将您的路由器限制在14 but。如果没有天线,这只是25毫瓦的功率(信号的实际功率取决于输入设备的dbm和天线的增益)。在美国,你可以被允许1瓦(1000 mW)或EIRP (这是整个“天线+发射机功率”公式,FCC用于调节功率为1瓦。无论如何,这也可能是问题的一部分原因。25兆瓦=1/40瓦,所以你的WiFi卡可能只限于窃窃私语。要解决这个问题,可以尝试破坏WiFi卡的管理域,iw命令中的txpower选项,或者查看路由器是否必须限制客户端的txpower。

我看到NetworkManager和wpa_supplicant都在运行。我的笔记本电脑(Inspiron 7590)与英特尔9560-ac无线网卡也有类似的问题。用wpa_supplicant代替NetworkManager后,事情就解决了。在此之前,我在互联网上尝试了每一个建议,但都没有成功。
编辑:问题是多个dhcpcd客户端。wpa_supplicant系统现在也是稳定的。
