Network not detected after boot

Hi so I have been in the process of reinstalling Arch and noticed that I could not connect to the network after rebooting. While booting from the USB media all of my network devices come online and work, but anytime I try and boot using my Arch partition my network devices are not even detected.

Here is the output for ip link while booting from live media

1: lo <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKOWN mode DEFAULT group default qlen 1000 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp3s0:<BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 
    link/ether 28:d2:44:00:b6:2b brd ff:ff:ff:ff:ff:ff
3: wlp4s0:<BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 
    link/ether 60:36:dd:81:14:ba brd ff:ff:ff:ff:ff:ff

Here is the output for ip link while booting from the partition

1: lo <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKOWN mode DEFAULT group default qlen 1000 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

Running ls /sys/class/net has the same results only displaying lo while booting from the partition. I have seen multiple threads where the issue was a missmatch between the versions of linux installed when running pacman -Qi linux and uname -a, but I have confirmed that the versions are the same. Any help is greatly appreciated.

Re: Network not detected after boot

Welcome to the arch linux forums akibby.  What is the kernel version the usb media is using and what is the version used on the installed system?
Also please include the full dmesg from the installed system and the output of lspci and or lsusb depending on how the network adaptors are connected.

Re: Network not detected after boot

So it seems like my previous statement about pacman -Qi linux and uname -a was incorrect as they are returning 4.13.11-1 and 4.7.4-1 respectively. I think before I ran that command while booting from the usb.

As for lspci I received this as the output

and lsusb returns

Re: Network not detected after boot

chroot in first making sure the system's /boot is mounted then reinstall the linux package if it is not in the cache use Pacman#pacman_crashes_during_an_upgrade.
