Everything was working fine up until today, I've been fiddling for hours trying to configure ethernet on my arch install with no luck. I run a dual boot system with windows and networking seems to be working fine there.
No matter what I tried every time I tried to ping an address I just got "network unreachable"
I tried booting from a live CD made using the same ISO that I used to make my install in the first place. That doesn't seem to want to connect either (although it worked fine when I used it to make my installation)
Following through the arch wiki I get the following outputs.
04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06) ... Kernel driver in use: r8169 Kernel modules: r8169
dmesg | grep r8169

From what I can gather this means the kernel driver has been loaded
ip link show dev enp4s0
2: enp4s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000 link/ether 50:e5:49:44:08:b9 brd ff:ff:ff:ff:ff:ff
Interface seems to be up but when I run dhcpcd I get an error
sudo dhcpcd enp4s0
enp4s0: waiting for carrier timed out dhcpcd exited
I also tried using the example ethernet-dhcp and ethernet-static configs with netctl (changing eth0 to enp4s0 for each config) then enabling and starting them with "netctl enable ethernet-xxx" and "netctl start ethernet-xxxx". That didn't return any errors but I still get "network unreachable".
