iperf Done. at least no retransmitts...but not the best transmission speed (on 18.4 i had ~930Mbit/s) will try before the first change in drivers/net/ethernet/realtek next https://wiki.ubuntu.com/KernelTeam/GitKernelBuild i used stable git-tree instead of mainline git clone --single-branch --branch=linux-5.4.y https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git and had to disable secureboot because of wrong signature-message on first boot...but at least easier than i thought... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1880076 Title: ubuntu 20.4 - retransmitts with r8169 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1880076/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
