My bthub6 has Wi-fi OK and two Ethernet connections, one via electricity main to PC and other to Netgear Arlo camera hub via direct cable. The Ethernet connections work if plugged in separately but fail within 5 minutes if plugged in together. Same effect if another Hub6 used. I can trick hub by using single connection to an Ethernet switch and connect my two Ethernet cables to that. Then works fine. But should not have to do that. What is going on?
