[SOLVED] Cannot connect via network manager (both wired & wireless)

Last weekend my system stopped connecting to Internet via either wireless and ethernet interface. When I plug phone via USB, nmcli has no problem connecting. Also 'dhcpd en0s25' works.

$ nmcli dev connect enp0s25
Error: Connection activation failed: (54) A secondary connection of the base connection failed.
$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    link/ether 02:42:46:11:0f:d8 brd ff:ff:ff:ff:ff:ff

When I was installing Arch some time ago, my ethernet interface's name was "eth0", now it's being renamed to "enp0s25". Also my wireless interface is renamed:

Any advice?

Re: [SOLVED] Cannot connect via network manager (both wired & wireless)

The interesting information will rather be in the journal than in dmesg (since the device works and this is a problem w/ NM)

I set it to connect automatically, this is part of journalctl, all the time repeating.

Now I'll be fighting with wireless. Hopefully reboot will help.

Re: [SOLVED] Cannot connect via network manager (both wired & wireless)

Wireless also works now. I don't know what happened, 1 hr ago it didn't connect, even after networkmanager reinstallation, restarting services etc.
Problem solved.

Re: [SOLVED] Cannot connect via network manager (both wired & wireless)

It could also just be an issue with NM's internal dhcp client, try to switch that to something more mature: https://wiki.archlinux.org/index.php/Ne … HCP_client

Re: [SOLVED] Cannot connect via network manager (both wired & wireless)

Oh yes, last thing I've installed was dhclient, but I didn't create or change dhcp-client.conf file as instructed in the link. How to check wchich DHCP client is NetworkManager using? In the global configuration file (/etc/NetworkManager/NetworkManager.conf) there is nothing besides some commented information about the file.

Re: [SOLVED] Cannot connect via network manager (both wired & wireless)

It will use the internal dhcp client by default
This is also indicated by the 

NetworkManager[3119]: <info>  [1528385781.5963] dhcp4

lines.
