Network Issues

All - Have assembled the HM, and can get the webpages to work, etc.

However, I am having intermittent issues with the wired networking, and wanted to see if anyone had experienced the issue.

Hardware;
Heatermeter PCB
Raspberry Pi
Enterprise grade Ethernet switch
Wall wart - 12v 1a
verified ethernet cable

The behavior is that the HM responds to pings for about 500-600 times, then is unpingable. Sometimes it returns, and responds, other times it never recovers. No WiFi adapter attached.

Any thoughts, or places to go to determine failure?

Thanks in advance.

Sounds like it is crashing. 1st think i would do is swap the power supply and if available, try a regulated bench supply.
