Dropped WiFi Connection

Furrye38 - thanks for the excellent response.  Unfortunately turning OFF MAC address randomizers and subsequently re-initializing the cell phone network settings (as suggested in another blog note) has not resolved the issue of the cell phone randomly switching from WiFi to 5G (Verizon) back and forth, probably 4 - 6 times a day.  Moving between the router and its two satellites sometimes seem to spur the problem but not sure.  So I am now investigating disabling all IPv6 which has been disabling on the RBE971 router.  So how does this translate into the IPv6 settings of the cell phone (Google Pixel 10 Pro)??  The cell phone is dealing with two networks, my WiFi (ISP Comcast) and the Verizon 5G cellular network.  If the RBE971 only allows IPv4, I have to assume that the IPv6 addresses are all coming from the Verizon 5G side of equation.  All the internet general inquiry solutions for disabling IPv6 on the Google Pixel 10 Pro point to APNs and there the path forward on the Google device hits a brick wall.  The suggested steps don't map into the Pixel 10 Pro.  Verizon is looking into it for me but it is possible that seeking to disable IPv6 on the cell phone is an invalid question or above my pay grade??
