Nighthawk RAX70 Compatible Modem

[RiaT]

I have just purchased a NETGEAR Nighthawk Wifi 6 Router (RAX70) after reading multiple recommendation about it.

Unfortunately, I didn't realize I needed a separate modem for it.

What reasonable priced compatible modem can I purchase for it?       

I am grateful for any advice.

What service do you pay for?
Who's your isp? those a kind of key questions. 

we usually recommend checking with your isp to ensure the device you're looking for is compatible.
