[PLUG] Internet access certificate issues

[Denis Heidtmann]

The router is out of service,  not powered.  Is there any way to diagnose
it at this  point, or would I have to place it back in service and observe
a repeat of the problem?  Or is the problem not in  the router at all; just
coincidence that it went away when I removed the router?  Clearly I need
some very basic understanding of how all  these things operate.
