Ethernet not auto connect at system start

Hello. my Ethernet cart is Qualcomm Atheros AR8161 Gigabit Ethernet.
this card is not auto connect to net at system start. so the power on process waste a long time.
with https://wiki.archlinux.org/index.php/Ne … figuration, I grep all about the ethernet card information.
then find it is not connect to net.

[justin@justin ibus]$ dmesg | grep alx
[    5.316641] alx 0000:03:00.0 eth0: Qualcomm Atheros AR816x/AR817x Ethernet [94:de:80:21:0e:12]
[    5.575598] alx 0000:03:00.0 enp3s0: renamed from eth0

run the command "ip a" , the enp3s0 status is DOWN. use "ip link set enp3s0 up && dhcpd" the card can connect to the server.

[justin@justin component]$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: enp3s0: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether 94:de:80:21:0e:12 brd ff:ff:ff:ff:ff:ff

how can I config the card auto connect at the system power on?

Re: Ethernet not auto connect at system start

How did you configure the system to automatically connect? Have you checked the network setup wiki page?
