Radio Frequency Interference in the 2 Meter Ham Band

We have the nighthawk AC1750 router. We are having Radio Frequency Interference on the 2 meter Ham band. (146.910 mHz) How do we solve this problem. Does this product comply with FCC regulations covering interference?

         C6300[v1] or C6300v2?  Look for "Model" on the product label.

         "MHz".  "m" = "milli" = 1/1000.  "M" = "mega" = 1000000.

         Visit http://netgear.com/support , put in your (actual) model number,
      and look for Documentation.  Get the User Manual.  Read.  Look for
      "Technical Specifications" and "FCC Part 15" (which you might want to
      review)?

         The usual Part-15 remedy is to remove power from the offending
      device.  You could try shielding.

         Harmless enough to try, but I wouldn't expect much output in the 2m
      band from a 2.4GHz or 5GHz transmitter, regardless of its channel.  I
      know nothing, but I'd expect signals in that band to be spurious stuff
      from the CPU and other computery stuff in the gizmo, rather than its
      wireless-network radios.
