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

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
I'm also affected by this bug. I'm using Wireless AC 5ghz on an Acer
Spin 5 which apparently uses the Ath10k drivers if that's relevant.
Ubuntu 18.04 is the most recent version of Ubuntu that I've confirmed to
not be affected by this bug. I have tested every release thereafter
(18.10, 19.04, 19.10)
This could be the same issue as those other two. Similar hardware is
involved. I haven't had time to test changing those settings on the NIC.

Possibly the same issue as bug #1666432, but I can't confirm that it
occurs on the wireless interface, just Ethernet interfaces.

This also occurs on wireless network connections, and *may* coincide
with my USB mouse seeing lessened throughput.
It appears to be weakly correlated with the amount of load on the
system. I see no evidence of it occurring at times when the system is
not in use.
