Check the following troubleshooting steps:
- Make sure that your latest drivers are installed. You can find drivers for Intel® Ethernet Adapters at the Intel Download Center.
- Make sure the properties of the Intel Ethernet Adapter are currently set to auto-negotiation.
- Check that your Intel Ethernet Adapter is connected to a fully compatible device with the speeds desired.
- For 10Gbps, check that a CAT-6 cable or superior is being used.
- Check the Ethernet adapter properties to make sure that it is being recognized with the correct speeds like, 10, 100, or 1000.
- A test with another computer or compatible device can be done to discard issues.
- If the adapter is dual port, an IP can be configured on each Interface and see the properties between them to check there are no issues with a specific port.
If after all these troubleshooting steps, the adapter continues with the poor performance, consider a replacement.
