I have an HP DL360P GEN8 with an Intel E5-2609 2.40ghz, 40gb ram.
I am running a samba NAS, Syncthing, and Plex. These all work fine except when it comes to my issue.
The issue: As soon as I start a file transfer (maybe 1gb) or run iperf3 or try to watch a movie over Plex the network connection drops for maybe 15 seconds then reconnects.
Network Hardware:
The machine came with a 4 port 1Gb ethernet NIC which works fine – except the disconnecting issue. I forget which model it is, but it has a driver or something that is known to have issues sometimes with ubuntu.
So I ordered a Dell 0FHNX8 Intel i210-T1 Single-Port 1GB RJ-45 PCIe NIC which works fine but SAME issue.
THIS IS NOT A CABLE ISSUE. As far as I can tell this has nothing to do with the ethernet cord. The server is patched from a short cat6 cable to an old adtran network switch through its gigabit port. (it is managed but I reset it a while ago and havent been able to connect to it so it is running as default). This then runs over a longer cat5e cord to a gigabit switch. I have other devices working just fine through this connection.
I even tried directly connecting my Mac laptop to the server with multiple new ethernet cords and experienced the same issue.
