I have been dealing with this off and on for a while now. I use a OWC Thunderbolt dock with an Ethernet port so I just use that one instead. I still experience some drops and I do think Eero is at fault here. Ever since Amazon picked them up my experience has gone downhill. I might start looking for alternatives.
Got a tip for us?

Mac Studios with faulty ethernet ports? Internet connection disconnecting periodically

Just to report that I am having same issue with Mac Studio on 2.5Gbps connecting to Zyxel 2.5Gbps switch with Cat8 cable. I was doing a ping test to the router and having a couple ping lost (Ethernet interface became disconnected in Mac) for 5 seconds and then comes back up over a period of 5 mins or so. I have to manually set the speed to 2500Base-T and "full duplex, flow control" , 1500 MTU in advance button > Hardware tab. That seems to solve my problem
Pretty sure this is driver issue in Mac OS. I am on OSX ver 12.6

And just to follow up on this, this has fixed it.I have been having this issue too, that I'm loosing internet sometimes on my mac studio where other devices on the network are fine. Just entered the settings into Network as described here so fingers crossed this fixes it
Many many thanks for posting this tip here. Wasn't sure if I had to try reinstalling whole system before finding this tip.
I guess apple would fix it eventually??? weird
I'm having this issue daily once or twice. VERY annoying. If I open aa terminal and enter "sudo ifconfig en0 down" and then "sudo ifconfig en0 up" it fixes it immediately, every time, so it's mostly an irritation and not a complete blocker. But it does seem to be a Mac Studio ethernet issue and I wish Apple would get on it and fix it. None of our other household Macs (several), iPhones, iPads, Apple Watches, or Windows machines have this issue.
Is this still happening to people?
Mine hangs for about 30 seconds, and this time I ran a ping test while things were frozen. Once test to Google's DNS, the other to another Mac on my LAN.
Seems like it's passing traffic just fine, am I reading this right?

It still happens to me on average of once per day. It goes down and it stays down until I run 'sudo ifconfig en0 down'. It's very annoying, particularly when it drop while I am streaming a live Formula 1 race!
I haven't had any problems on mine, after I did the manual Hardware settings on the interface.
It didn't solve my connection issues however by accident (I guess) I closed out Safari having numerous tabs open and then reopened it going back to what I was doing and it solved the problems. Works every time too, I can be streaming content from any web site and it suddenly freezes up or my internet connection seems to be down. When I check other open Apps they work just fine and there is/was no interruptions.
For me anyway it seems Safari is my problem and when I close it down and reopen it works just fine. So I give up for now and hope somehow it gets fixed with a future update.

I am hoping this is fixed in Ventura 13.1. I am also wondering if Power Nap or Sleep is suspect as mine went completely offline after the screen locked (even though I have "Prevent Mac from Sleeping") checked off. Otherwise I will try to manually set the network settings as described above.

I have re-wired my house twice now, purchased and replaced ALL my patch cables THREE times, tried two different switches (because why can't the Eero have more ports I have a NAS so I need a switch in place). I am convinced my issues lie with the Eero routers. They have just gone downhill. I will be planning to get rid of them in a few months. Its ridiculous as I spent $500 for them.
Eero support is useless. "Oh just keep trying switches, we can't see anything on our end". Yet even when I take the switch out and leave my NAS offline, I still have issues. How many of you have Eeros?

I set the following settings and the seemed to help for awhile. I matched them on the router.
Somehow my “prevent computer from sleeping when display is off” was unchecked and I had missed setting the Display to never turn off.
I am still thinking it is related to sleep and power. I think preventing the computer from sleeping and setting the screen to never turn off will fix it.
If fixing the sleep settings doesn’t take care of it I might try a usb mouse jiggler or a stay awake software like Amphetamine.

So, the settings above seem to have done the trick:
1.) Manually set the Network settings according to above screenshot and previous examples in this thread on both your Router Port and Network card on the Studio.
2.) Set the Studio to never Sleep, the rest of the screenshots above.
I really think there is a bug because the Network card eventually goes to sleep even though you set it not to in the Hardware settings. So, the solution is to keep the entire machine awake. I would appreciate it if sleep could be turned off for the Network card only.
I've been having disconnects on my M1 Mac mini, but only wth Citrix Workspace VPN. Everything else has remained intact. Even when my VPN goes down, my machine is still connected to the internet.* I have had some uncorrectable codewords with my cable internet, so I'm thinking it's a problem with my service, but nonetheless I have been looking into Ethernet issues.
*Normally I run with Ethernet as the primary network connection and WiFi as the fallback secondary network connection. However, right now for troubleshooting, I'm running WiFi-only to see if there's any difference in behaviour.
Could it have anything to do with IPv6? I came across this report:
apple.stackexchange.com
I ran into this same issue on a WiFi/Ethernet connection with my M1 Max Mac. The Wi-Fi and Ethernet conflicted with one another, and it has to do with how it renders IPv6 addressing on Monterey. My modem automatically refers to IPv6 in its DNS settings, so there was no need to have MacOS try to do its own.
There are two ways to fix this:
Set IPv6 to local-addressing only. Click System Preferences > Network USB/Ethernet selected > Click the "Advanced" button. In "Configure IPv6:", change it to "Link-local only" or "Manually". Don't change any other settings by hitting OK, then Apply. It'll remove the additional settings it doesn't need. You might also want to turn off Wi-Fi when you're connected to Ethernet so the two don't conflict.
You can also specify that the USB/Ethernet and Wi-Fi connections remain separate connections so they don't conflict with one another. (This is optional--step 1 should fix itself, but it adds additional fixes so the two connection types don't conflict.) You do this in the Network section of System Preferences, which explain it here: https://support.apple.com/en-us/HT202480
Create two locations: One labeled "Wireless" and another labeled "Ethernet". Then, you remove the Wi-Fi connection out of the Wired location you create, and remove the Wired connection out of the Wi-Fi location. Then, when you need to change, click the Apple Menu, hover over "Location" and then click "Wireless" or "Ethernet" depending on your connection method.

I've seen this and it's quite annoying - click on a link - it's dead. Type in an address - no response. After a while you get a bad gateway error or it suddenly loads and acts like nothing happened. Just like a bugged network connection.
However, jumping over to Chrome or Firefox, they work just great.
Since jumping over to the 13.1 update I haven't experienced any loading errors or disconnects. I hoping this means it's been fixed. You are correct this is/was only occurring in Safari.
Glad I found this thread. I’ve been having these occasional lock-ups using a wired ethernet connection too.
i’ll try some of the fixes suggested here, and see if they improve things

We have two identical MacStudio. Both connected to a 10 gigabit qnapswitch which connects to 10 GB NAS.
One MacStudio has zero issue, the other one suffers from this. This should be a hardware issue for sure.
Is this problem solved from Apple side do I need to do something manually on the Mac which has a problem?

true, could be a hardware issue on either the switch or the studio side
three places to check
swap ports at the switch
swap cables at the switch
swap cables at the studios
does the issue follow the studios if you swap the ethernet cables between the two machines?
or does it follow the cables?

Getting intermittent pack loss on 10GbE M2 Studio ethernet port after coming out of power-saving mode. Taking out ethernet cable and plugging it back in fixes it until next time. But very annoying. Connected to Unifi 10GbE Flex XG.
Will have a look at debugging over the next week or two and let you know what fixes it, if anything.
