Can't get an internet connection using WiFi or Ethernet

I've recently put an SSD in a laptop that I've installed Arch Linux on before. When trying to install Arch this time I can't establish an internet connection via ethernet or wifi. I've noticed when booting the USB ISO it gets stuck for a bit on

  [*** ] A start job is running for dhcpcd on enp3s0.

I've made sure the modules drivers were present

 Kernel driver in use: r8169
           kernel modules: r8169

It is also the same for my wifi network controller, iwlwifi is in use.

For wifi, it fails to connect after using wifi-menu -o, and then after using netctl start <myprofile> it exited with an error code. I entered systemctl status netctl@<myprofile>.service

What I got back is:

archiso dhcpcd[968]: wlp2s0: soliciting a DHCP lease
          archiso dhcpcd[968]: timed out
          archiso network[853]: DHCP IPv4 lease attempt failed on interface 'wlp2s0'
          archiso network[853]: Failed to bring the network up for profile '<MyProfile>'

I thought it was due to faulty hardware but other Linux distrobutions detected the wifi, and worked with an ethernet cord. So, I am not sure what is happening here. I've installed Arch on this laptop before with no problems. Any help would be appreciated.

Looks like there is a problem with either your DHCP server or dhcpcd.

Have you tried to set the IP address manually?

ip addr add <local_ip>/<subnet_mask> broadcast <broadcast_address> dev enp3s0
ip route add default via <gateway_ip> dev enp3s0
