There are 20 or so devices with red “!”, mojority of my total system. When I select Query, System Busy progress bar appears and goes from 0-100% in 5 successions and disappears with no message and the “!” does not disappear, I will connect the Izy PLM to another power source with a long extension cord to see.
The system has been stable till 30 days ago when I changed ISP and WifI MODEM and relocated my computer to a new office within the house with new wiring. Changing powersource to the PLM from the old part of the house does not help clear messages. What are typical sources of line noise in a household setting? I have no high amp motors or magnetic energy devices outside of AC compressors.
