Hello writer,

What about the LED of the hub? Is this one also off? If yes the following problems with your hardware are very likely:

1. The port of the hub does not work correctly. Try to change the port.

2. The Ethernet cable is faulty or the wrong (possible crossed). Try to use another cable.

3. The hardware of the board isn’t initialized correctly. Normally not possible with the factory settings. Perhaps a damaged board.

In the past I had a problem with a notebook and a crossed cable. The board wasn’t powered up when starting the notebook. To save power the notebook verified that there is no Ethernet hardware installed (installed yes but not powered up) so the notebook switched the complete Ethernet hardware off. All worked fine when powering up the board before the notebook.

Bye,
