I have multiple devices on a single Netgear R7800 and the Pixel 3 is the only device I see that is randomly disconnecting multiple times a day. I see about a dozen disconnects at random times. Other devices include phones (Galaxy S8, iPhone 8) and non-phones (Home Theater, Chromecast).
The default logs on both OpenWRT and Android do not show a reason for these disconnects. I'll post the logs from each device.
OpenWRT:

Versions:
OpenWRT 19.07.02 (started with enabling WPA3 with 19.07-rc*)
Pixel 3 Android 10 March 2020 update
Is there any logging change to either device to see more output?
