Arch Linux 不再连接到 Wifi

Question

我已经使用 Arch Linux 一个多月了。我曾经wifi-menu连接到我的 Wifi 网络。我每次启动笔记本电脑时都会运行该命令。

wifi-menu 当我尝试连接时总是出现此错误：

Job for netctl@HelloWorld.service failed. See 'systemctl status netctl@HelloWorld.service' and 'journalctl -xn' for details.

问题是每次启动时我的界面都打开了。所以我用这个把界面放下：

ip link set down wlp2s0

wlp2s0是我的接口名称，HelloWorld是我的 Wifi 网络的 SSID。

---

这一次，不管把接口放下，它都没有连接到网络。它给了我上述相同的错误。

这是输出systemctl status netctl@HelloWorld.service：

netctl@HelloWorld.service - Networking for netctl profile HelloWorld

journalctl -xn 给我这个输出：

systemctl 给出了/run/dhcpcd-wlp2s0.pid不存在的错误，它不存在。尽管/run/dhcpcd.pid确实存在名为的文件。

这是网络控制器的输出 lspci -k

我已经从互联网上尝试了一些东西，但还没有找到解决方案。

有没有办法解决这个问题？或者我可以在 Arch Linux 中重置与网络相关的所有内容，以便我可以wifi-menu再次连接到网络吗？

谢谢！

Answer 1

我遇到了完全相同的问题。你杀了dhcpd？

我完全杀死了 dhcpd：

$ sudo killall dhcpcd

禁用无线接口后（也$ ip link set down $应该可以工作）：

$ sudo ifconfig wlp3s0 down

我的 wifi 菜单又开始工作了。

Answer 2

为什么每次启动时都运行wifi-menu？除非您经常连接到新的无线网络，否则您应该简单地使用 wifi-menu 一次创建配置文件，然后使用netctl在您启动时自动连接。
