Thanks Ron.  I think you provided a good solution.  I really appreciate your help.  All three PCs do show the device with its IP address on my wifi network.  I also hunted down almost every device listed on the network identified by Glasswire and my modem/.router.  .  The device shows up on all three PCs and also on the modem/router. Glasswire reports only a tiny bit of traffic - just a few bytes.   I have been tracking down the MAC addresses and discovered a couple of thermostats and a wifi light switch I forgot.  (Good learning expereince),   I did think of changing the WIFI name and password or using MAC blocking on the modem.router.,   I will check out the Glasswire forum, thats a great suggestion.  I came here to Dell first as I thought that this was a Dell feature..  Anyway a good mystery and as I said a good learning experience for me   Thanks So much V49
Hello I was conducting some due diligence on wifi security and noticed a couple of 'unknown' connections both through my modem/router and Glasswire Firewall software.  One is identified by Glasswire as - Gaming console, Delta Electronics.  I looked up the mac address and it confirms that is a Delta Electronic device but does not tell me what it is.  My guess is that it is something to do with a cooling fan in the computer, an XPS 8940.   Other than this i have no idea what it could be.  I have checked and cannot account for ever installing this or giving it access to my wifi. Any ideas?  Appreciated V49
