The problem continues with 4.15.0-65-generic. This is a ping summary coming into the affected system from another host on the same network segment with no connectivity problems, reflecting a four-minute period of recurrence (ping times were <1ms for the last 20 seconds or so, but while the problem was occurring, there was ~50% packet loss and >200ms response times for the packets that did get through): --- [host] ping statistics --- 258 packets transmitted, 146 received, 43.4109% packet loss, time 259396ms rtt min/avg/max/mdev = 0.109/377.848/641.641/190.332 ms Note that network-manager has been purged from this system, so this is not a network-manager issue. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1804280 Title: intermittent periods of packet loss and high latency Status in linux package in Ubuntu: Confirmed Status in network-manager package in Ubuntu: Confirmed Bug description: Intermittently and unpredictably, ping response times and packet loss will spike to unusable levels.

[Touch-packages] [Bug 1804280] Re: intermittent periods of packet loss and high latency
At one point in my in-home streaming past I had to set the BSSID to my current router's IP address which resolved latency problems. I have multiple routers on my property with the same SSID, this is to provide wifi coverage to the entire property. I had to change the BSSID to the router I was using at any given time.

[Touch-packages] [Bug 1804280] Re: intermittent periods of packet loss and high latency
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 Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1804280 Title: intermittent periods of packet loss and high latency Status in linux package in Ubuntu: Confirmed Status in network-manager package in Ubuntu: Confirmed Bug description: Intermittently and unpredictably, ping response times and packet loss will spike to unusable levels.

[Touch-packages] [Bug 1804280] Re: intermittent periods of packet loss and high latency
** Description changed: Intermittently and unpredictably, ping response times and packet loss will spike to unusable levels. Normal ping times are about .25 ms for other hosts on the local network, with essentially no packet loss. During the problematic periods (usually lasting 2-10 minutes), packet loss jumps to about 50% and ping response times on the packets that aren't dropped jump to between 250 and 750 ms. This behavior started when I upgraded from Kubuntu 16.04 to Kubuntu 18.04. Changing which host on the network I test this with has no effect (and during this, those other hosts are able to use the network without any problem). Replacing the cable changes nothing. Using a different Ethernet interface changes nothing. Replacing the switch changes nothing. This is almost certainly not a hardware problem. There is a chance that using wireless instead of Ethernet would fix the issue, but I have been avoiding that since the wired connection is much faster when Kubuntu is not malfunctioning.
