NetworkManager连接不上wifi

本来连接得好好的,突然网断了,然后删掉这个wifi重新添加,提示我找不到这个wifi,但我换用netctl却没有问题,可以正常连接。
PS:使用的桌面环境是KDE(Plasma)

看下 NetworkManager 有没有扫描到你的 ssid

# 获取所有网络设备
qdbus --system --literal org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.GetAllDevices
# 然后拿到设备列表一个一个执行下面的命令,执行成功的为无线设备,失败的忽略
qdbus --system --literal org.freedesktop.NetworkManager <Device> org.freedesktop.NetworkManager.Device.Wireless.GetAccessPoints
# 这会得到此设备扫描到的ssid列表,然后在一个一个执行获取名称,得到的是 Byte Array,最后看看有没有你自己ssid(Byte Array格式的)
qdbus --system --literal org.freedesktop.NetworkManager <AccessPoint> org.freedesktop.NetworkManager.AccessPoint.Ssid

或者安装一个 network-manager-applet 用它来看下你的 ssid 存在不

或者看下你的 ssid 频段,最好在 1-11 之内

我执行完了第一个命令,得到了三个device,然后只有第三个可以成功运行第二条命令,但返回结果如下:
AccessPoints
[Argument: ao {}]
没有什么AccessPoint值。

意味着 NetworkManager 没有找到可用的 ssid,更改下 wifi 频段试试。
看下 NetworkManager 的日志,看看有没有报错,命令:

sudo journalctl -u NetworkManager -r

Re: NetworkManager连接不上wifi

用rfkill list命令看设备状态,有可能是被WiFi功能键给锁死了。
PS:NM的这个问题很普遍,换netctl是最简单的办法。

0: hci0: Bluetooth

        Hard blocked: no
1: phy0: Wireless LAN

        Hard blocked: no
看结果并没有被锁啊,而且被锁的话netctl也是用不了的,我自己尝试过

我研究了一下,我在开启NetworkManager之前用rfkill检测网络是没有被锁的,但当我sudo systemctl start NetworkManger(就是这句话导致wifi被锁),sudo systemctl stop netctl以后再rfkill,就显示wifi被锁,不知道是什么原因

Re: NetworkManager连接不上wifi

下面这样做管用不?

在笔记本上关闭WLAN

有时候在你使用笔记本上的开关禁用WI-Fi然后重新启用后,NetworkManager无法工作。这常常是rfkill的问题。 $ watch -n1 rfkill list all 检查驱动rfkill是否通知到无线适配器的状态. 如果你开启适配器后,其标识符仍然显示blocked,你可以尝试如下命令手动unblock(X是前一条命令的identifier编号)

# rfkill event unblock X
