Thank you for contacting Intel Communities.
I am sorry to hear you are having issues with the Ethernet LAN controllers.
Can you please provide the following information (from both devices) to better assist you?
- Is there any LED activity on the Ethernet port?
- Is the LAN enabled in the BIOS>Devices>Onboard Devices?
- Is the BIOS up to date? (version 0062)
No LED activity.
LAN is enabled in BIOS.
Currently BIOS Version 59.
I'll update the BIOS and see what happens.
Updated BIOS to 62. No love. No LEDs. Nothing at all in Device Manager, not even an "Unknown Device". It's like the network card doesn't exist.
