I have two NAS units: a Synology and a QNAP. They are both connected to my router via a switch, but since both have spare Ethernet sockets, I guessed that they could also be connected directly, offering independence from the router and perhaps some speed improvement
I connected two sockets using a 2m length of Cat 6a straight-through cable. The LEDs at both ends lit and flashed correctly
But rather than enhancing the network as I had intended, I am now unable to connect to the router and one of my NAS units from a browser
I realise that my expectation may have been simplistic, but I don't know what to do now to fix the network. I will try giving IP addresses to the two new connectors, but otherwise I can't think what may help, beyond removing the new connector
Can someone please suggest something more intelligent?
