Orbi assigning 1 satellite out of range address

Even though I had rebooted the Orbi router several times and had done a factory reset of the miss-addressed satellite several times over many hours of pulling my hair last night, this morning I reset the satellite one more time and it miraculously got a new address in the right range.  I have no idea why.  (I have Google Fiber and the modem is just a modem.  The Orbi is the only router giving out addresses on my network.)  I have seen this behavior one other time on my mesh where it took about 8 hours or so for the Orbi router to give the second wired backhaul satellite a  proper address.  This is using latest firmware V2.7.3.22.  The other wired satellite gets assigned a correct address right away.  They are not daisy chained.  And the satellite getting the right address first is not always the same satellite.
