Maximus XIII Hero: Both ethernet ports don't detect cables

[dsatfire]

Hello,

I've recently purchased a Maximus XIII Hero and am having trouble getting internet connectivity. Originally, I could not get any network connectivity, but was able to resolve this by plugging in an old Optical Drive to install the Wifi drivers from the provided CD.
The main issue that I'm having is that neither one of the ethernet ports are detecting cables inserted into them. I tested the network using another PC and was able to determine that the network and cabling are not to blame. I've also uninstalled, reinstalled, and updated the Windows drivers, so that is not the issue either. Windows recognizes both ports exist, but they are in a perpetual "unplugged" state. I've also updated all firmware to the latest versions in a attempt to fix this.
In my other Maximus Hero (older model), I can see the LED indicators flashing when a cable is plugged in even before loading the operating system. With this newer board, I don't see the indicators go on at all.
Is this a faulty board, or is this something I can fix without having to ship off the board and waiting for a replacement?

Trying to use the existing copy of window 10 that was on my SSD (coming from a Z390) I NEVER got the integrated network to work properly.
That is until I reinstalled windows from scratch, then it worked fine out of the box ¯\_(ツ)_/¯

On my system, the port I have disabled in the Bios does not blink, the active one does.. Do you show both Ethernet ports in the Device Manager?

I have the Z590 E Gaming and I'm also unable to get the ETH to work (cable not connected on both ports). I previously had the Z490 and faced the same issue. Theres something about this i225-V Controller that does not like me at all.
Z490 had the Rev2 and Z590 has Rev 3.

Have 2 different notebooks which both work flawlessly connected to the ETH cable (switched already cables and ports on my switch but still no "heartbeat")

Update:
My house was build in 2018 and every room has a RJ45 wall plug. The wires from the wall plugs go in a central box where my router is located. There I can "patch" every single room directly to my router.

ETH will not work when the cable is plugged into the wall socket but, if I plug it directly into my router (so basicaly moving my router out of the central box where my PC is located) the ETH suddenly recognizes the cable.

So there you go, poor cabling from the wall sockets.

What do you mean with poor cablingfrom the wall sockets?

2 other Notebooks see the cable and work flawlessly and also another 2 earlyer builds with Realtek ETH Controllers also worked before. Why wouldn't the I225-V (3) do it?

Yes, some devices work with improperly connected RJ45 cables, some do not. Turns out the i225v is one of those who needs all pins connected in the correct position to work.
The other solution would be to check both the pinout of the wall sockets and the patch cables, but if the wall socket is not connected properly then it might be impossible to replace all the cables inside the walls or re-do the sockets themselves.

All cables are connected. This has been tested with ETH cable tester. Don't get me wrong but the instalation has been done by qualified workers and the cables are industry grade (orange) cables with metal RJ45 sockets. Those cables are way thicker then normal Patch cables and are way better shielded. Also the distance they run does not exceed 6m which is nothing.

You might want to try different patch cables in the closet and from the wall to the computer as well. Even if they work with another device there could be weird issues like the RJ45 is slightly out of spec and not making contact. I had a problem recently where I was getting intermittent horrible speeds and after testing a bunch of different things it turned out to be a faulty surge suppressor. Sometimes it's something you'd never expect.
