Wired Connection No Longer Working

As of roughly 1 week ago, I am no longer able to access the internet with a wired connection.

Output of

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
2:  enp0s31f6:  <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
      link/ether 60:45:cb:6f:1c:ff brd ff:ff:ff:ff:ff:ff
3:  wlp3s0:  <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
      link/ether 3c:a0:67:69:65:b1 brd ff:ff:ff:ff:ff:ff

What's strange to me is that when I

ping 8.8.8.8

it just hangs, and

ctl+C

returns, for example,

14 packets transmitted, 0 received, 100% packet loss

, and not

Network unreachable

.

dhcpcd enp0s31f6

only returns

sending commands to master dhcpcd process

If I remove my wired ethernet cord and

ping 8.8.8.8

, it does return

Network Unreachble

.

Does anyone have any hints as to what is going on here?

Please paste the output of:

uname -a && pacman -Q linux
systemctl list-unit-files --state enabled

Moving to NC...

Re: Wired Connection No Longer Working

What is the output of `systemctl status dhcpcd`?

Have you tried enableing the service for a specific instance? https://wiki.archlinux.org/index.php/Dhcpcd#Running

Re: Wired Connection No Longer Working

If you have a router try restarting it and see if it helps.  Sometimes my old router won't respond correctly to dhcp requests.  If I pull the plug and plug it back in, everything works again.

Re: Wired Connection No Longer Working

Still no luck after restarting/ pulling the plug a few times.
