[SOLVED] RPi3A+ Network instability.

[Tim Curtis]

These types of network issues can be difficult to troubleshoot but let's take a step back to summarize things and see where that leads.

1. Pi-3A+
a. with r839 Bullseye drops off the network
b. with r9 Bookworm drops off the network
c. with plain RaspiOS no issues

2. Pi-4B and Zero W no issues

3. Virgin Hub 3 Router
a. Post describes wireless settings for addressing wifi dropouts
https://community.virginmedia.com/t5/Net...-p/5397800
b. Using only as a Gateway now with Linksys M2000 for wireless

The approach I would take is to analyze the success case #1 c.

1. Is it RaspiOS Lite, same kernel and OS version as moode 9 ?
2. Compare the NetworkManager connection file on RaspiOS vs moode 9 and If there are differences make the moode 9 file the same and then re-test.
sudo ls -l /etc/NetworkManager/system-connections/

Other things that can be tried

Install moode-player package on plain RaspiOS Lite. If no wifi dropouts then I can look at our image build. It's done using essentially the same pi-gen tooling thats used to make Raspberry Pi OS but there could be diffs.

I'll run one of my systems on a 3A+ and see what happens over the next couple of days.
