RAX120 router and NIGHTHAWK AC1900 A7000 adapter compatibility issue

Hello Everyone,

I had picked up a RAX120 from Best Buy to upgrade my home network to WiFi 6. Considering there is no WiFi 6 Adapter, i had also picked up a A7000 Wireless adapter from Netgear.

Now I have been facing several issues with this setup.

1.If i turn on AX mode on the RAX120, the A7000 adapter does not even see the WiFi networks for the RAX120

2.The A7000 refuses to detect the WiFi if HT160 is selected for 5GHz, I changed to HT80 mode.

3.I have tried to enable/disable 20/40MHz co-existence but no luck

How do I get the maximum performance gains out of the RAX120 using the A7000? 

Both are on latest software versions.
