Computing equipment in my case is wireless and router; PC in another room

various; 2634-sss outdoor module; 2466d; toggle linc dimmer & 2456d3 Lamplinc - Currently have PLM plugged into wall, cable to ISY and ISY cable to router; wondered if it made sense to relocate everything away from router to PC, at least to test; not sure if the system will work that way Thanks for input TInk

Did a factory reset, appeared to have completed successfully. Restored a backup, that worked. However, I have the same few devices that are not connecting, cannot find Insteon Engine. Two of the three are on a remote control and works fine. Totally puzzled.

I have had my hub for several (3+) years. Hub is isy994i . Firmware is 4.6.2. I have about a dozen devices running now. Never really experienced any issues over the time. I have connected and disconnected devices over time. Couple months ago we had some kind of power disruption and several of my devices could not connect. I fooled around with the devices for a while and everything was fine. Several weeks ago we had two power disruptions one just a few minutes after the first. Once everything came back up there are three devices that will not connect. During trouble shooting I tried deleting one device; when trying to add back I get the "cannot determine insteon engine" error which is on the log as an error 3. Similar error when trying to reset the other two devices. I have moved the interface to another wall outlet in the same room, still no success. I did that as I read it was most likely some kind of communication issue. During this time the programs continue to run correctly with no issues. We did add a wireless camera system just before the power failures. I don't know if there could be a conflict as they are both on the same router. Not sure what to do at this point. Looking for some pointers. Thanks Tink
