Default Marvell Gigabit controller stuck at 100Mbps

My NAS is a Windows 10 1909 64-bit PC running on an EVGA Z68 FTW motherboard which uses a Marvell 88E8057 network controller.

The problem is that the network connection is stuck at 100Mbps. That really sucks when I'm trying to move large files around.

I tried a few different network cables, I tried moving it from my Asus router to my Netgear switch (both of which are obviously gigabit).

Driver version is 12.10.16.0 which was automatically installed by Windows. EVGA's website lists an older version than that. Marvell's website lists 12.10.17.3 but when I try to install it, it says "a newer version is already installed"

Not sure what the next step is besides putting in a PCI-E NIC which I really don't feel like doing.

It wouldn't bee the first time a Windows driver has screwed up an ethernet connection.
Uninstall the Windows driver and install the one from the EVGA website.

I would be pissed and think of wiping the drive and reinstalling Windows.

Especially Windows 10 with Windows Update errors.

Yes, I borrowed my friends furry friend and tried to shove it in the second Ethernet port because the motherboard has too. Unfortunately, I got a hissing noise and some scratches, and my friend is now angry at me.

Did you try setting the speed to 1000Mbps manually?
It's quite common to have auto negotiation issues with gigabit Ethernet.
Intelligent switches and most NICs have some options to change to alleviate that

Nope, in the drop down on windows I can't pick gig. Only 100 or autonegotiate.

try a linux livedisk,
try a new cable - check it has all 8 wires connected.
100mb does not use all 8, 1000 does.

if you still cant get it going, check the transformer on the motherboard and any asociated ceramic caps.
if the chip cant detect all 8 lines it will not run at 1000.

incidentally, most marvel chips can run a cable test and even have a built-in TDR function.
try tracking down the software - i think asus used to supply it with the top-end athlon boards.

Cable would be my #1 suspect as well...I've ran into this a lot over the years.

maybe the pins are bent in the marvel Ethernet port? seen that and the actual port being worn out (from plugging in and out too many times). Other than that I guess drivers. Maybe a boot linux from a stick and retest.
