I have been experiencing identical issues since around mid-January or so (though my latency sometimes reaches 3000/4000+ ms during these times). I am running a freshly installed and fully updated version of Ubuntu 18.04 Desktop. For the first couple of months after installing 18.04 I had none of these issues whatsoever, they seemed to materialize during a period when I was doing a lot of heavy software development which used a great deal of system resources (multiple VMs). Originally the workstation was wired directly to my router, but even after purchasing a wireless USB adapter I am still experiencing the issue.
I typically use remote viewing software to work on the affected workstation (from another laptop in my home), and once I begin to notice moderate sluggishness in the response time of the system I can typically run "sudo systemctl restart network-manager" and I will usually not begin to experience the issue again until several hours later, typically. If I go too long without running that command the full 10-15 minute period of extreme latency will set in. It doesn't return fully to "normal" response times after that high period, but it is far lower than the most extreme patches. I hesitate to say that the issue is similar to other bug reports because of the "dropping of the connection" aspects of those. The connection never fully dies in this case, but just experiences periods of latency related unusability. Any logs or further info available upon request. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1804280 Title: intermittent periods of packet loss and high latency To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1804280/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
