Sounds like a bad motherboard from the get go? I have the same board but no problems at all with my ethernet. The most annoying problems I have right now are the slow 1 minute post and my cpu cooler not quite beefy enough to keep it fully cooled... next paycheck..
FWIW, I have the Intel Ethernet Controller I225-V with the Intel driver, 3/5/2022 version 22.214.171.124
Dunno if any of that helps?
windows 11. My computer specs are in my profile.
I try the driver version you use "126.96.36.199" and the problem is gone for now but why you use this driver version because on the armoury crate and the asus website have the version "188.8.131.52"?
dunno what to tell you on that, didn't notice before you said it. Armoury crate does indeed "SAY" I have 184.108.40.206 INSTALLED, however it does NOT appear to be true. I'll note this version of Armoury Crate seems to be buggy as it is. (and it is up to date) ... probably something Windows Update did?
Device Manager says 220.127.116.11 (Intel driver)
I just put together a new Windows 11 system based on the Rog Strix X670E-E Gaming motherboard. I have been troubleshooting a wired network problem this week. In short, the Intel Ethernet i225-V (rev3) drivers (18.104.22.168 and 22.214.171.124) do not work well on transmit/upload traffic across the Internet for me (weirdly, internal home network file transfers work fine).
I've tested the same physical cabling with multiple other systems and they work fine (Windows 11 also but different wired NICs).
Running the same network speed and copy tests when booted from a Ubuntu live USB shows no problems.
During the Win11 build I didn't notice a problem as I was mostly just downloading apps/drivers. When I started gaming (MSFS/PUBG/DCS) and transferring files up to Google Drive I noticed the network on transmit would fall off to almost nothing. This was confirmed with speed test runs as well.
At least the WiFi connectivity works great, but I have a wired connection and I want to be able to use it.
My next step is try to flip through more Intel I225-V Win11 drivers in search of a fix. Anyone run into something similar on these Intel I225-V NICs?
Did anyone try the Intel prescribed fix - firmware update required!
