I am struggling to get additional Ethernet access when I add a Switch to the Hub. I am using a TP-Link and can see that the hub has connections, however at the device end I am getting Unidentified network and my Ethernet is only blinking orange. I have reset the Hub, turned everything off, but still cannot get it to connect fully.
Is it a managed or unmanaged switch. If the former, have you configured it correctly, if the latter, it might be faulty.
Have you tried a different ethernet cable and different ports on the hub & switch?
