X870E Nova: Ethernet adapter does not appear

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello. 

The internet adapter is enabled in BIOS, but it is not shown in device manager, making it impossible to install. 

I have tried:

- Windows 10 and Windows 11

- Bios 3.15, 3.16 and 3.20

- Disconnect PSU for several minutes

-Clear CMOS

For what it's worth, let me say that there is no led on in the internet port, and I have tried with the network cable connected and disconnected. 

Please, help.

	Does anything show up in Device Manager at all, with a ? mark, indicating the device is missing the driver? It might show up in "Network adapters" or in "Other devices." If it shows up there, then it's likely a driver issue, but if it doesn't show up at all, then it's likely a hardware problem.

	Thank you, I had already checked everything you suggested. I have processed the RMA, it seems to be a hardware problem.

	My LAN hardwire Ethernet is connected but the only way I can use my hardwire is if I power down my PC and disconnect my power cable for 45 seconds and then reconnect it. After I turn it back on it detects it. Every time it powers down to sleep mode, I have to repeat the whole process all over again. It's frustrating. I need a solution.
