Problem with utp connection to my desktop

[SirJohnes]

My desktop has a problem connecting to the modem via utp, but my laptop (with the same utp cable) can.
My desktop is connected with two cat6 to my modem, desktop to wall, wall to modem. When I boot my pc the connection switches between "no cable" and "identifying network". After 20 seconds of switching it hangs on "identifying network" and finally ends with "Unidentified network". When looking at the ipconfig, the IPv4 address is a APIPA address. The weird thing is, when I connect my laptop with the same cable it works immediately.

While troubleshooting I connected my desktop directly to the modem with a cat5e cable. It connected directly. I also tried a different cable between the wall and my desktop, the same issue occurs.

My motherboard has a Intel(R) I219-V network adapter.
All the cables are new and recently installed.

Did you try installing the Ethernet driver? Sometimes that's necessary.
