RAX29 WiFi 6 Router not connecting at WiFi 6 with my laptop

Back to my original question:  Why does my Guest 5GHz network use the AX protocol while my Primary network (using the "Smart Connect" option) at 5Ghz use the AC protocol?

My Equipment consists of:

1. CM1100 Modem
2. AX2400 WiFi Router (RAX29)
3. Intel Wi-Fi 6 AX201 card inside my Windows 11 laptop
4. ISP is Xfinity
5. All hardware has most up-to-date drivers & firmware;  Windows 11 24H2 is also up to date
6. Both Netgear Modem & Router installed with basic, factory settings
7. the RAX29 was set up using the Nighthawk App and the option to have Smart Connect enabled on the Primary network
8. FWIW, the default gateway on my home network is 10.0.0.1, not something I selected but was "there" when I plugged in the Modem and it was activated by Xfinity
