Maybe the differential pairs? no this is not the problem. When booting the OpenWRT based system I can communicate with the device via the switch. (Didn't test deeply, but my Laptop got a dhcp lease from the Turris Omnia and I can ping it.) But this convinces me, that the hardware is good enough. If you have any ideas what I can try to make the switch work or help to diagnose the problem, just let me know. Best regards Uwe
