In the hours of 11PM to 6AM my ethernet will just randomly stop working. I know it’s not my router or my ISP because my phone can connect just fine and all it takes is a restart and my computer will reconnect to ethernet just fine.
I tried disabling power saver for the ethernet but it’s still happening. I can’t figure this out. Any advice?
You don’t get some sleep? 
So you are certain that the phone is using pure wifi and not mobile data at this time? Do you have mobile data on the phone turned off? What logs did you read to lead you to this conclusion and can you share them?
What about settings in the router itself. Have you checked to make sure it’s not set to turn off internet to the ip / mac address of connected computer?
If I may clarify @ncsurses, restarting the router fixes the issue (temporarily)?
Restart my computer, restarting the router does not fix the issue.
Given restarting the computer seems to resolve it, that would seem to suggest it is something related to the computer.
I’d suggest that at the moment you notice this issue, you grab the system log and see if you can spot anything network related in the later entries around when you noted the issue:
journalctl -b -0
I’ll do that when it happens again.
useless thoughts from vaguely been thru this before–
I’ve had to clear dns cache before…and fixed going offline.
I’ve had something that caused resolvd service to stop. had to flush or do something to it to get back online.
When I had WIN next to Linux a long time ago and WIN update would sandbag the Linux internet connection and clock (not your case)
had something that stopped networkmanager service once. I remember so little about that
twice I cured this offline thing by simply unplugging all cords, “letting the gremlins out”
only once in my history was this intermittent…and that might have been hardware-related
your outlier: intermittent
I really wish I was the note-taking, record-keeping type when it comes to Linux problems I’ve fixed but I’m not that guy.
Babbling only in hopes something might lead you closer to the answer
also check out your network settings. I do this when this sh** happens. I have no idea what I’m looking at, ever, but I will play around.
It just happened again. Here’s the output of journalctl -b -0:

It’s ok that you cropped the boot-log to the errors, as there would have likely been 80 minutes worth of unrelated noise.
It would be good however, to see the events that lead into this error as that’s sometimes a clue. So maybe 50 or so entries in the lead-up to the beginning of these errors, if you can share that too?
Could you please also share the output of:

Thanks for sharing those details.
You can reference that older log with journalctl -b -0 by adjusting which boot to reference. So -b -0 is the current session, -b -1 is the previous session, and -b -2 is the one before that, and so on.
There is a BIOS/UEFI update available for your motherboard:
https://us.msi.com/Motherboard/MPG-X670E-CARBON-WIFI/support
Some people have had success disabling Energy-Efficient Ethernet (EEE) on their Realtek RTL8125. The user azerb123 here shared how to do that.
You can first see if EEE is active:
sudo ethtool --show-eee enp16s0
You might see something like:
EEE settings for enp16s0: EEE status: enabled - active
If it is enabled, you can temporarily disable it for this current session only, using:
sudo ethtool --set-eee enp16s0 eee off
If you find that fixes the issue, you can make it permanent.
I’ve not tested this, but adjusting what azerb123 shared for your situation, to make it permanent, you’d create and edit a file called /etc/systemd/system/disable-eee.service like this:
sudo nano /etc/systemd/system/disable-eee.service
And populate it with this:
[Unit]
Description=Disable Energy-Efficient Ethernet for enp16s0
After=network.target
[Service]
Type=oneshot
ExecStart=/usr/sbin/ethtool --set-eee enp16s0 eee off
RemainAfterExit=yes
[Install]
WantedBy=multi-user.targetLooks like disabling ethernet energy efficiency did not resolve the issue.
I went ahead and installed my Bios update and I switched to r8168-lts. We’ll see if those fix it.
Someone with similar errors like your
https://bbs.archlinux.org/viewtopic.php?id=307785
Some kernel parameters to try:
r8168.aspm=0 r8168.eee_enable=0 pcie_aspm=off
Good luck!
The craziest thing that happened to me recently I had a breaker pop and when I reset it my internet didn’t work.. keep in mind sometimes I have intermittent issues. Turns out the ethernet was barely connecting with the router up high and cables dangling down. Some of the cables are probably pretty old so I just push them in so they make better contact. No more connection issues. 
Yeah, the Bios update did not work nor did installing the latest driver from the Realtek website. I still randomly DC because my ethernet dies.
After switching to 8169 driver I seem to no longer have the issue.
