I’ve noticed via Netdata that I have a packet drop rate of above 50% (~1200 packets) when the pi is “idle”. The percentage adjusts downwards with more activity but the packet drop count of the last 10 minutes stays the same (1200).
This is on a fresh install with: Pi-Hole, MineOS, Netdata
I happened to have a similar experience in a fresh install of DietPi v6.31. Interconnection was sporadic even when the pi4 2GB was next to the router. Youtube for example would never have trouble as it was able to fill the buffers periodically, but downloads, which need constant connection(with a download manager with resume support), would fail almost always.
Solution: I upgraded to v6.32 with fresh install and that fixed the problem for good for me.
