Hi, I change for example dns in networkmanager, when restart NetworkManager , "systemctl restart NetworkManager" the network not works... [maykel@maykel-arch ~]$ sudo systemctl status NetworkManager ● NetworkManager.service - Network Manager Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service; enabled) Active: active (running) since mar 2014-04-08 12:24:13 CEST; 19s ago Main PID: 3082 (NetworkManager) CGroup: /system.slice/NetworkManager.service ├─1223 /usr/bin/dhcpcd -B -K -L -G -c /usr/lib/networkmanager/nm-dhcp-client.action enp4s0f2 └─3082 /usr/bin/NetworkManager --no-daemon abr 08 12:24:22 maykel-arch NetworkManager[3082]: <info> (enp4s0f2): DHCPv4 client pid 3093 exited with status 1 abr 08 12:24:22 maykel-arch NetworkManager[3082]: <info> Activation (enp4s0f2) Stage 4 of 5 (IPv4 Configure Timeout) scheduled... abr 08 12:24:22 maykel-arch NetworkManager[3082]: <info> Activation (enp4s0f2) Stage 4 of 5 (IPv4 Configure Timeout) started... abr 08 12:24:22 maykel-arch NetworkManager[3082]: <info> (enp4s0f2): device state change: ip-config -> failed (reason 'ip-config-unavailable') [70 120 5] abr 08 12:24:22 maykel-arch NetworkManager[3082]: <info> NetworkManager state is now DISCONNECTED abr 08 12:24:22 maykel-arch NetworkManager[3082]: <info> Marking connection 'MO2O' invalid. abr 08 12:24:22 maykel-arch NetworkManager[3082]: <warn> Activation (enp4s0f2) failed for connection 'MO2O' abr 08 12:24:22 maykel-arch NetworkManager[3082]: <info> Activation (enp4s0f2) Stage 4 of 5 (IPv4 Configure Timeout) complete. abr 08 12:24:22 maykel-arch NetworkManager[3082]: <info> (enp4s0f2): device state change: failed -> disconnected (reason 'none') [120 30 0] abr 08 12:24:22 maykel-arch NetworkManager[3082]: <info> (enp4s0f2): deactivating device (reason 'none') [0] I have reboot my computer for network on again.
