7410 Wifi connectivity issues

Dell 7410 has integrated Intel AX201 NIC. Driver v22.250.
This NIC allows 3 wireless modes, AX , AN, and N.

My Wifi router is Netgear Nighthawk R6900P. AC1900 Version 2.36.
On the default mode, AX, frequent drops to our router. In addition, other devices, such as smart TV are impacted and drop signal when  the Dell is on Wifi. 
Switching to AN reduced but did not completely fix issues.
Switching to N seemed to have fully resolved.
