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.

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

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.

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.
