Intel Ethernet Controller (3) I225-V Connection Drop

[Woozie]

Hi, first of all I would like to thank Intel for producing a great network card. Thanks also to MSI for using this excellent network card in their excellent motherboard.

I'm using the MAG Z690 TOMAHAWK WIFI DDR5 model. I just recently built my computer. The I225-V is really a nuisance. Since the first day I built the computer, even though I tested all the drivers of Windows 10-Windows 11 and tried functions such as turning off the power management, it never came to a solution. As a last resort, I'm thinking of sending the motherboard back and getting a new one. This will be a bit of a hassle for me.

Isn't there a solution to this?

Quick update. I spent hours of troubleshooting this on my NUC.

My issue was the network cable. After I switched it to an older cable my dropped connection stopped. Hope this helps.

I tried that. It didn’t help.
