Nighthawk CAX30 AX2700 connection issues with DHCP and IP address reservations

I have the same issue you are having with your CAX30; "Nighthawk CAX30 connection issues after reserving DHCP IP address reservations under LAN Setup". 

The only different is that my wired devices do connect to the router, but they can't access the internet and most of the wireless devices are unable to connect to the CAX30 after I start to reserve IP addresses.  

I provided the Level 2 technical support team all my logs and diagnostic information from my router for the engineering department to diagnose and they can't locate the issue with the device.   They also told me that none has reported the issue I'm experiencing with this router.  And just like you, the router works fine with working internet after I reset the device and I don't reserve IP addresses under LAN Setup.

Also,  Netgear replaced my router after I contacted support months ago about this issue, and the replacement router is having the same exact problem.   A new firmware was release on 9/2022 ( V.1.4.10.10) but it doesn't fix the connection issues when reserving addresses.
