That WiFi Problem With the Two Lenovos

The intermittent problem returned.  Actually, it never went away.   It just held connection longer.  So I took the repaired one to church. It connected to their WiFi and stayed connected. Something about the Sparklight mesh WiFi system is incompatible with the Lenovo WiFi in the 11e and Yoga 9, but not the big Lenovo or any other device in the house.
