Using a TP-Link TL-WDR3600 without any other switch in between, shielded cables. I also tested other 4 routers from TP-Link (Archer series) and got the exact same result.

And no, till this RTL8125 NIC I never ever had any similar issue. Funny thing is that I tried a normal Realtek PCIE Gigabit card in my system and worked perfectly.
Interesting, I wonder if a different soc would react differently. What was the pcie card you used? Fyi I don't have any issues with my unify board so far.

Hey. I had the original NDIS problem and the router/switch issue. (Temporarily solved by the settings earlier in this thread - so far!!)
Running driver 46 and Aorus B550I Pro Ax
My switch would go down every time I tried to torrent using qBittorrent. It's a TP-Link 8 port switch connected to a TP-Link mesh. Interestingly the mesh survives and all I would need to do is repower the small switch. 20 minutes later it would go down again.

I can't believe the issue is this pervasive and they haven't fixed it.

Don't think there is any relation between vSOC and ARP / STP loopbacks. But yes, I tested different vSOC and same thing.
The pcie card is just an ordinary 15 bucks tplink gigabit pcie NIC with a realtek chip. Works perfectly.
So far heard about very few people with X570 Unify reporting this. And no B550 Unify users at all. Makes me wonder if indeed there is an issue with producers who didn't follow Realtek specifications (that's what Realtek said 6 months ago).

It is said that only realtek has 2.5G NIC card, not intel in the market (intel 2.5G nic was not mass produced yet.)

Update from my friend:
The issue is caused by 2.5G Realtek NIC, because it's framework is different from 1G Realtek NIC (eg. 8111x card). The new beta driver has workaround the udp load issue, but the ARP issue(others reported) is still recurring. But it is difficult to duplicated.

I have summarized my issue to realtek by mail (you can find it in realtek website, nicfae@realtek.com). Maybe we can provide our issue info (how to duplicate, 100% to see the issue? or 50%?).
Besides, ordering another usb nic dongle or new nic card is the quickest way to playing my WOW, sadly
Just sent my case regarding ARP loopback to nicfae@realtek.com and told them how to replicate it.

I just got an answer from mr. Kevin Cheng, in which he wrote:

Hi,
Thank you for your information. We will try to reproduce the issue. Could you help us to dump all registers(by RtkHwView tool) and capture wireshark log for our reference?
Wireshark: ( https://www.wireshark.org/download.html )
1. Options: Select the RTL8125B(G) to Capture on B550 platform
2. Start: Start to Capture the Ethernet packets until the issue occurs

3. Just save as a pcapng file

RKHView Tool


Sadly I can't help anymore since I returned the board and asked for a refund, but if anyone can make this little research regarding the ARP loopback problem, please contact him at nicfae@realtek.com.

Ladies and Gents, so here is what I have discovered: I have tried several different options for bypassing the onboard NIC. USB Ethernet dongle, still get the same results, although it did use RealTek drivers. Intel w/intel drivers, of course, PCI NIC, still get the same results. Why would this happen?

For comparison, I have a second computer that gets near 1Gps DL (intel adapter). My current computer used to get that until a week ago.

An update regarding the Realtek 8125 NIC ARP Loopback issue:

It is NOT solved in the 10.046 drivers and still brings down the router and the entire network.

After talking with mr. Kevin Cheng from Realtek in several emails, the discussion basically evolved in such manner that he basically aknowledged that Realtek didn't fix the ARP Loopback thats blowing up networks and routers. Which, by now, we do know. The sad part of this, however, was that he somehow implied they didn't even know about this, which is beyond idiotic ; reddit and motherboard forums are full of complaints about the RTL 8125 various issues, including the ARP / STP Loopback.

Have they given you any idea on a timeline for this to be fixed?

I have opened a tix from MSI. Since I am under warranty my MoBo is heading back. I'd be surprised if they can fix it. My current build is less than 6 weeks old and this happened.

No timeline, last time I asked the guy for more info, he stopped writing to me. Reminded me of Svet, the forum admin, who also had a very nice incentive, some weeks ago, talking with us regarding this and then too disappeared. :)

Regarding fixes, dunno what to think other than the ball is clearly in Realtek's courtyard ; it's possible that they will fix the driver and everything will be ok, but, same time, it's also possible they will never fix it.

Do you guys know of a good PCI network card that I can get? Does Intel sell standalone network cards?

Yes they do, search amazon for one, get anyone that intel is still supporting driver wise. Driver support: https://downloadcenter.intel.com/download/25016/Ethernet-Intel-Network-Adapter-Driver-for-Windows-10
Thanks.
Is there a downside to just purchasing an Intel card and using it instead? Aside from the fact that I'll be spending money in fixing realtek's problem. Do I lose performance somehow? Can I have 2 NVMe drives + a PCIe 4 GPU and also the network card? Just in case

Also, I currently have a 600 Mbps connection and it's likely that my provider will upgrade me to 1 Gbps soon. Which card would you recommend? I assume I should go for 2.5G

Now that depends on your motherboard and setup. If your motherboard supports that set up, and you get an intel card with good driver support; then performance will be good. Getting a 2.5 card isn't that easy and you need the rest of your network to be able to use it fully. I wouldn't bother and just get whatever intel chipped card you can get in your region; that has driver support.
