Maestro lost Internet on WIFI ... connects but no Internet

My Maestro reports "Connected but no Internet" when it connects to my WIFI hot spot.  Prior to leaving home for several days it worked great, I turned the Maestro and 6400 off while gone but when I got home this problem was presented.  I wonder why it will connect to the WIFI but not resolve the Internet, all of a sudden? 

I have always had a WIFI booster that extends the range of the WIFI.  I tried connecting the Maestro to the booster SSID rather than the main hot spot and surprise, the Maestro connects and sees the Internet just fine.  The main hot spot has a full bars signal, greater than the booster where the Maestro is located.  So how can the Maestro resolve the Internet through the booster which itself connects through the main hot spot to the Internet, but can not resolve the Internet through the main hot spot itself?  This is sort of maddening. 

Yes all my other devices such as laptops, Roku TV, Amazon Alexa, WIFI thermostat, cameras, and so forth all work great connected to the main WIFI hot spot, but the Maestro lost it's ability to do so.  Yes I have rebooted the WIFI hot spot, the Maestro, and the 6400 several times to no avail.  My laptop running SmartSDR works with the 6400 just fine.  Help please!
