Don't like what I'm reading about Intel I225-V Ethernet Controller.
Just don't matter the motherboard model, even the Brand, just search for I225-V bandwith problem, drop conection problem, and so one and you'll see we are experiencing huge problem.
Mine is a brand new Asus ROG Strix Z590-E Gaming with an Intel I225-V Ethernet Controller rev.3! These problems occur since rev.1! 2020!
Already try a lot of things, nothing that solved it.
