(1) Remove all the dual-band devices from my network. And you were right, no difference.
(2) Plugged the EZIO2x4 right on top of the PLM. No difference. In the Insteon Traffic window, lots of lines.
(3) Reverted back to SHN v2.0. Everything started working again.
(4) Moved the EZIO2x4 back to where it was, across the room, different circuit. Still Worked.
So, it looks like a v2.03a problem. Although even with v2.0, I’m still getting inconsistent results reading Link Tables. Maybe I’ve got some other interference going on.
How am I supposed to set the ‘Links Database Size” when reading link records? Small, medium, large? What difference does this make in the comms?
