Ow great, I have the same issue with a Pi 4. I've just put it as my main router. It happened overnight, network just stopped working.

This USB NIC is connected to internet provider router and the onboard NIC to my private network (I use a mini PC, Gigabyte Brix, as a home router/server). I've tested one week ago with another USB 3.0 Gigabit NIC, which has a different chip from Realtek, and the same thing happened, so something is going on here. Also, I've tried a fresh install of Ubuntu 20.04 (server) and the same thing. Another thing I've tested is to switch Nics, the public and the private, same problem. Any idea how to fix this? Is a mayor problem really. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.21 Architecture: amd64 CasperMD5CheckResult: pass DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2021-12-06 (2 days ago) InstallationMedia: Ubuntu-Server 20.04.3 LTS "Focal Fossa" - Release amd64 (20210824) Package: linux (not installed) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=es_ES.UTF-8 SHELL=/bin/bash Tags: focal Uname: Linux 5.15.7-051507-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lxd plugdev render sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1953554/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
