PSA: Intel I226-V 2.5GbE on Raptor Lake Motherboards Has a Connection Drop Issue: No Fix Available

[robal]

Someone on Reddit claims that changing from 'Autodetect' to '2.5 Gbps Full Duplex' is a workaround.

Can anyone with the issue confirm this ?
That would be enough for me to justify buying z790 board now.

Possibly irrelevant, but the thing with the AX2x1 chips, they use CNVi, versus the AX2x0 chips which are PCIe x1. The AX2x1 chips are used in systems that have the Wifi integrated into the chipset, while the AX2x0 chips are used in systems that don't have integrated Wifi.

More basically saying - AX201 is a radio module for CNVio controller, while AX200 is a standalone solution with built-in controller. I have AX200 card as well. Only working in PCIe_x1_2 with X570 Aorus Pro. PCIe_x4 is completely dead. PCIe_x1_2 doesn't accept other cards. 2023 and AMD still can't get their chipsets under control.

I doubt that's an AMD issue, this might be Gigabyte's fault, or the board is damaged. They are known for making a lot of problematic motherboards over the last like 7 years, since Z170 era.

Just after AMD AM5 launched last year I picked up an ASUS ROG STRIX X670E-A GAMING WIFI for a 7700X. It has an Intel I225 2.5G LAN (I225-V rev 03) and I'm using Linux. If I let the NIC go into power saving, it never returns, and only a reboot brings the connection back. For the first two months I had to reboot it daily. Now that I have the right kernel incantation to stop the buggy parts via Reddit discussion, it seems reliable enough. But I have both a 2.5G Realtek PCI card and a USB NIC on hand on the assumption one of these days I'll find another showstopper bug I can't fix. Quite the inversion from the Linux days where I checked all motherboard purchases to make sure they had an Intel Gb NIC instead of a Realtek...

Now would be a good time as any for AMD to leverage their Xilinx acquisition and show up as another player in the networking space, especially as they're focused on the commercial/enterprise sector, and have it trickle back down to consumer level.

The times we live in!

Sorry, no time to meme it properly while on phone.

Can you share the model?

Yeah.

Amazon.com

Sadly appears out of stock right now.

Wouldn't that just introduce more overhead and additional points of failure?

I've been using usb ethernet adapters for years since most corp ultrabooks dropped ethernet. They work well, as always just buy a reputable brand.

*Up to 1Gbps. After that it becomes hell. Overheating and connection drops galore. Check the web if you don't trust me.

AMD does not run intel nics

Yes it does.

I have a hard time believing this issue affects all i226-V NICs. ServeTheHome has tested multiple firewall PCs with i226-V and I'm sure they would have noticed dropouts.

New Fanless 4x 2.5GbE Intel N5105 i226-V Firewall Tested (servethehome.com)

theres compatibility issues with certain switch hardware configurations when using auto negotiated port settings.

Amusingly, the issue doesn't manifest when you connect an i225 to an i226

Oh, I imagine that's the case, I wouldn't use them to be the backbone of my home server, that's for sure. But for daily office work and what most people do online, they are very good.

Still for what I little I know about 2,5GB and 5GB, they are quite the crappy standard, I've read nothing but problems about them. On the other hand, seems like 10GB is for the most part ok.

Yeah, no. I won't be happy if my VPN drops because of the adapter. Also, stay away from 10Gbps even if you run nothing critical on it.

I've been dreaming about having a 10Gbps network now that Synology has an adaptor for their new NAS units. What's wrong with 10Gbps?

I meant that there are many issues with 10GbE USB-to-ETH adapters. There is nothin wrong with 10GbE per se. Due to (mainly) client limitations I too use mainly 10Gbps links around home.

Ahh, yes USB adaptor issues. Thanks!

Sad to see this from intel. Really was hopping the l226 didnt had as much issues as the l225 had on release.

Now i got two build on the way, both with l226 nics inside, that ill have to get some PCIe I225 v3 or B3 stepping cards, so they are network reliable.

Do you guys think this could be fixable with drivers?

Wondering how is the Realtek Dragon RTL8125BG?

It's software is bad it seems.

Reading that post it basically confirms that it may not drop out any more (small sample size) the other thing is that this is only tested at 1Gbps by reading that post.

So its better, but I wouldnt say "fixed" yet

There's nothing wrong with the i226-V controller itself, so it's entirely possible you won't have a single issue. The most likely causes of the issues are a bad batch of controllers (unfixable through software), bad implementation on motherboard (potentially, but unlikely, fixable by software), and/or problems with the software stack itself. Until the actual root cause of the issues is determined nobody has a clue as to what may permanently resolve whatever is being experienced. There are several potential solutions and if you end up being one of the folks having problems it doesn't hurt to try them.

This is what happens when the bean counters take over from real engineers.

Wondering how is the Realtek Dragon RTL8125BG?

I have a B650 board here with an RTL8125 onboard. So far, no issues at all. Rock solid stable.

It's software is bad it seems.

Not from what I can see. OK sure, the add-on Dragon whatever software sucks but the driver itself is fine and that's all I care about. Is it stable? Yes.

For what I know about 10GbE, they have been around for 20 years in IT environments while 2,5 and 5 are just a step down from that intended for home users and is still quite green, that's what I meant. I can't imagine anything >1Gb in USB form being decent enough too. I don't really have read enough into things above 1GbE since I don't really have a use for it, but probably I would go directly to 10GbE if that was the case.

Since Mac mini M1/M2 have an option to get 10Gbit Nic and we have problems on PC with 2.5Gbit nic-> what the hell is going on.
We should have already 10Gbit Nics as standard for PC.
Apple Mac Mini M1 10GbE Gets 10Gbase-T

Use cases
You have local network with NAS on 10Gbit....
Some internet providers already have modems with 2.5Gbit nic

I meant that there are many issues with 10GbE USB-to-ETH adapters. There is nothin wrong with 10GbE per se. Due to (mainly) client limitations I too use mainly 10Gbps links around home.

I think on professional server side you are using pcie 2 x 10Gbit nic cards. Nobody is using USB to nic:
