Hello Christopher, thank you for triaging.
1) No. LAN only cycles the connection when setting the MTU. Setting MTU to "automatic" (= the default) works fine. 2) I tested with the daily-live-ISO (downloaded at 06/16/2018). With this version the LAN interface worked without connection cycles - even if I changed the MTU. For further review, I have also tested with Xubuntu 18.04. Again, the LAN interface showed no connection cycles after changing the MTU. Additional information: My currently installed and fully updated version 17.10 still shows the problem. It looks like the bug is fixed from version 18.04 on, so I will update to Xubuntu 18.04.1 soon.
