NETGEAR disconnected from internet, sync etc, when AirPort Connected

[alexxmc77]

Hi,
I’m asking Apple this also, but the second I plug in my AirPort Extreme router into one of the Ethernet ports on my Nighthawk D7000, is Nighthawk disconnects from internet and sync fails etc. the only way to resolve, is to restart and disconnect the attached airport

Please don’t say ‘don’t use it then, etc’

Any ideas would be excellents

can you make the airport a AP only?
