AX2700 - 5G wifi stopped broadcasting

I had nothing but problems ever since i got this netgear CAX30. Its a $300 router and i am very frustrated with all problems it has since the day i got it. Every few months i have a new issue with wifi. now all of a sudden the 5G network is no longer broadcasting. Tried changing to different channels, mode, transmit power but had no luck. Reset the router .. yet again. Still no 5G network. downgraded the firmware from v2.2.2.2 to V1.4.10.10, no 5G. Anything else i can try.
