Deco XE75 and Windows 10 (Intel I211) unable to auto negotiate / use 1Gbps on 2nd ethernet port

So, I've finally decided to update my Deco XE75s after a long long time. And I regret it.
The primary issue I am running into is that the 2nd ethernet port on my secondary Deco (which has a wired backhaul to the primary Deco), can't auto negotiate with my Windows 10 PC. When I manually set the speed to `full duplex 100mbps` it works, but using `1Gbps` or `auto negotiate` fails.
I placed a switch in between and it magically started working using 1Gbps. Furthermore, removing the switch again and using the 3rd ethernet port on the Deco magically fixes the issue. I connected another Windows 10 pc to the second port and it auto negotiates to 1Gbps just fine.
Does anyone have any clues about what could be causing this? Or is this just some weird firmware behavior? Everything worked just fine before the update.
