Hi,
I have a fresh installation of Home Assistant version 0.113.3 on a PI4 with 4GB. I have been debugging an issue of my Hue light bridge becoming unavailable every other minute. I came across a networking issue and wanted to ask a separate question.
The pi is connected directly to the router via Ethernet cable and it’s a stock Virgin Media router. At the moment I only have hue light integration. When pinging the server continuously from another pi on the same wired network I get Destination host unreachable e.g.

I would appreciate some further advice on this. In particular, I do not know how to verify if it’s a router or my pi problem. I tried pinging the other pi via wireless network and apart from consistently higher latencies (expected!), I am not getting host unreachable problem. Therefore, I am leaning towards pi problems. Is there any further information I can extract from HA logs?
Please let me know.
