I have a base M2 Pro and does not exhibit any packet loss on ethernet. It's going back as I need/want more RAM. Hope the replacement doesn't have this issue.

I have not reinstalled the OS since receiving either just turned it on and setup/updated it.
 
So, folks -- I'm fairly sure this is a software issue.

If you go to settings->network-><ethernet interface>->details->hardware and then change "Configure" to "manual", THEN change *ANY* setting (I turned off ABV/EAP mode), save/exit and then go in and change it back; the packet loss seems to stop. (I also tried changing duplex to 'flow control' and back again, just incase it helps anyone)

I'm guessing the auto configuration has gotten something wrong and persisted it somehow. Try it out!

66 packets transmitted, 66 packets received, 0.0% packet loss
Mac mini M2 Pro. Been fighting RDP issues for a week (figured it was the RDP software/settings, but worked fine with the M1 Mac mini. Was having a 40% packet loss with the M2. Turned off the AVB/EAV and seems to have went away.

Turn it back on and leave it in manual, it should still work fine
 
Did you restore from backup/transfer from another Mac Uniq? Or "fresh install"?

Thank you sir. This workaround fixed the issue for me. I had to leave the setting on manual.
Got a new Mac mini M2 Pro last week and had the problem after using Migration Assistant the first time. Even completely erasing the SSD and reinstalling macOS Ventura didn't help.
 
Has anyone bothered reporting the problem to Apple? Seems like a rather serious issue to have made it through QA for launch.

I have reported it to them but I guess there will be no answer. They probably won't act until a lot of people report it.

I got a call from them because I was returning it at first , I told them about the fix and the thread on the apple forum

how do you report it ?
 
To get "real" network security you are going to either set up something like PFSense (and maybe pay for a snort license) or buy an actual SOHO/SMB grade device with a subscription to services like Intrusion Prevention, Antivirus protection, malware protection, C&C Botnet protection, etc.

What's the difference between PFSense which recommends netgate small office to large businesses hardware and an "an actual SOHO/SMB grade device with a subscription to services like Intrusion Prevention, Antivirus protection, malware protection, C&C Botnet protection, etc."?

Commercial grade devices have access to threat feeds that are better than snort, they have additional capabilities like full SSL inspection and a whole host of features that most home users would never need or care about. I would say if someone is willing to put the work in to get PFSense working and maintain it that is an excellent low cost option for “real” security.

At the low end of commercially available devices you can look at something like a Sophos or you can go up a bit and get something better from Fortinet, Palo Alto or Checkpoint. Many of these are also available as VMs.

Many Thanks !
 
I'm getting horrific network results on both wifi and ethernet on my M2 Pro Mac Mini. I've tried the Network settings workaround posted by @cyberpunk_ber above, and I'm still getting 2.2-4.3% packet loss on ethernet.

Compared to my 2016 MacBook Pro with 0.6% loss on wifi.

This problem is more like I’m downloading a 10mb file in 5kb speeds on Ethernet
That was the problem
WiFi was working fine
Did you leave it in manual setting ?
 
I haven't noticed any lag with my ethernet in use just to be safe I tested my Mac Mini M2 Pro and got no packet loss. I did a fresh install. no backup restored.

Downloads speed wasn't much of note (I wasn't watching closely, though speed tests said it was fast), but downloads were constantly dying for me, e.g. "unexpected EOF" or they'd just stop without warning.

I left it on manual, which is literally between 10-20x better, but still 4.6% loss is a lot. So I put it back to automatic and I was getting 0.6-0.9% packet loss for the better part of a day. Awesome, problem solved...until the next time I powered down and back up again. I was back to having 73.8% packet loss. Was able to reproduce that again with another power cycle. Unfortunately, that workaround isn't holding up on Automatic as well now as it did last time. It has to be on manual, and even then, still get some bad loss, just not in the double-digits.

I had a call with Apple senior support and sent them a packet trace and sys diagnose. They will follow-up in a few days. Hopefully we'll see if they can provide a more permanent fix.

Questions for all:
1) did this happen before updating to Ventura 13.2 or only after? I only noticed it after, and presumably the issue would have been so bad that downloading the update would have been impossible. Though, updating to 13.2 was the first thing I did, so it's hard to say if it was fine before the upgrade.
2) Does powering down for a few seconds and back up again make the issue come back for you too?

My 16GB M2 Pro had the ethernet issue with the factory Ventura 13.0. The issue actually kept me from downloading the 13.2 update until I performed @cyberpunk_ber 's manual fix.
