you may be write take it up with Asus I was on ADSL+2 I had an asus dsl ac3100 it had channels 12& 13 for asus / NZMaybe, they're distributing the EU version to us now.
My previous Asus routers, had channels 149-161.
I'm not sure if Netgear's newer routers have the same restrictions.
Luckily, It has DFS channels, so that's fine for now.
