Hi everyone,

I am trying to understand a strange Ethernet compatibility issue between my PC onboard network card and my TP-Link router.

My PC has two Ethernet adapters:

  • Onboard NIC: Intel(R) Ethernet Controller I225-V from Gigabyte Aorus Pro X
  • USB-C Ethernet adapter

I also have two routers:

  • Huawei
  • TP-Link

And I tested using the same Cat6 cable in all scenarios.

Test results

With the Huawei router:

  • Huawei + Cat6 + onboard Intel I225-V = works
  • Huawei + Cat6 + USB Ethernet adapter = works

With the TP-Link router:

  • TP-Link + Cat6 + USB Ethernet adapter = works
  • TP-Link + Cat6 + onboard Intel I225-V = does NOT work

Important detail

When I connect the TP-Link router to the Intel I225-V onboard NIC:

  • the link LED does not turn on at all
  • Windows shows “media disconnected”
  • Linux also shows no link
  • I tested more than one LAN port on the TP-Link router, with the same result

So this does not look like a DHCP/IP configuration problem. It seems the Ethernet physical link is not being established at all between the TP-Link device and the Intel I225-V onboard controller.

I tested this on Windows and Linux

  • Same behavior on both systems
  • Since it also fails on Linux, I do not think this is only a Windows driver issue

My questions

  1. Has anyone seen a compatibility issue between TP-Link Ethernet ports and Intel I225-V controllers?
  2. How do I fix this :

Have you tried to test with a different ethernet cable (for example the one in the TP-Link router kit). CAT5e would do the job.

Hi  @terziyski ,

I have tried with the cable that came with the router, with my cat6 and with an old cat5 that I have here, same result.

That's rather unusual - your best bet would be to contact your local support for further assistance.

  @terziyski after a long dialog with chatgpt / claude and gemini they all are saying that I should buy an unmanaged switch because this is a negotiation problem between my NIC and the TPLink router.

I will buy just for the sake of test, but it is far from the solution that I want.

That's would I thought as well, hence asking you to try with a different ethernet cable.

If you have a spare switch around you give it a try, or if you can borrow one from a friend.

Indeed buying a switch is far from an ideal solution. Usually a negotioation issue comes to a limited negotiated bandwidth speed.
