[Bug 1754759] Re: LAN connection keeps connecting and disconnecting in an infinite loop
Markus Baumann: >"Does it make sense to try the mainline kernel, since the error is obviously fixed with 18.04?" No, it doesn't. Given you reproduced this in 17.10 (which is EOL July 2018 as per https://wiki.ubuntu.com/Releases ), when you upgrade soon to 18.04, the issue would be gone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1754759 Title: LAN connection keeps connecting and disconnecting in an infinite loop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1754759/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1754759] Re: LAN connection keeps connecting and disconnecting in an infinite loop
Does it make sense to try the mainline kernel, since the error is obviously fixed with 18.04? Unfortunately, I also do not know how to try the mainline kernel. Can I test this with a live image (I do not want to destroy my production machine)? Is the mainline kernel compatible with 17.10? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1754759 Title: LAN connection keeps connecting and disconnecting in an infinite loop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1754759/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1754759] Re: LAN connection keeps connecting and disconnecting in an infinite loop
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.

[Bug 1754759] Re: LAN connection keeps connecting and disconnecting in an infinite loop
Markus Baumann, thank you for reporting this and helping make Ubuntu better. 1) To clarify, if you don't adjust the MTU does the LAN network still connection cycle? 2) To see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? ** Tags added: bios-outdated-2.72 regression-release ** No longer affects: network-manager (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1754759 Title: LAN connection keeps connecting and disconnecting in an infinite loop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1754759/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
