I'm using Unraid version 6.9.2. The problem I'm having is whatever network card I set as the main one I get sporadic connectivity. If I connect with a secondary card it works fine unless I try to access network shares. It connects then disconnects and cannot ping. I've changed the ports it connects to on the switch, I've changed network cables, etc. It has to do something with the operating system. I've added different network cards and change their priority but it still has sporadic connectivity. I can't ping it and then all of a sudden I can. It's just hit or miss connectivity. This is a Dell server R710.
