@Roland, I tested on a T14 Gen2 laptop and a T15 Gen2 (share the same i219-v card to T14), cannot reproduce this issue so far.
the logs you attached seems based on Ubuntu 21.04 with 5.11.0-16 kernel, since this laptop certified with Ubuntu 20.04 with 5.10.0-10xx-oem kernel, could you pls attached those logs after the test in comment #29(Ubuntu 20.04 plus 5.10.0-1026-oem)? thanks. ** Changed in: oem-priority Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927925 Title: Massive network problems with I219-V on Thinkpad T14 Gen2 (e1000e) To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1927925/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
