[SOLVED] When changing from wireless to wired connection, dhcpcd ti...

When I connect LAN cable and I boot my laptop, dhcpcd starts normally.
But after I boot my laptop, dhcpcd timed out when changing from wireless to wired connection.

dhcpcd[400]: enp3s0f1: waiting for carrier
dhcpcd[400]: timed out
dhcpcd[400]: dhcpcd exited

Symmetrically, dhcpcd starts normally when changing from wired to wireless connection.
Please help.

What are you using to control your wireless networking?   systemd-networkd? netctl?  NetworkManager? wicd?
Is the wired connection being handled by the same program?
How are you starting dhcpcd?  dhcpcd.service? or are you letting one of aforementioned programs handle that?

I'm using NetworkManager to control wireless.

I didn't know NetworkManager uses dhclient.
So when I disabled dhcpcd.service, it solved.
