Hi, Thank you very much for your feedback.

Do you use any network switch to build the Ethernet Backhaul?

If yes, may I know the model number of the switch?

And can I have a picture of your current network topology?

Are you able to constantly reproduce this issue?

Wait for your reply and best regards.

  @FishWhisperer I have a trio of XE75s and I've just had to start an RMA because all my ethernet ports stopped working after a scheduled restart. The only way to fix the network was to swap the backhaul ethernet cables to different ports, but then half of my other wired devices stopped working too. Not even a factory reset got the ports working again so I have no idea what caused it.
