Netgear EX6120



The product page for this device says that it is AC1200 while the support page says AC750.
 * The hardware supports AC1200 so we'll assume that's the true spec.

This model shares a design with the Netgear EX3700 but uses different RAM/Flash sources.

The Netgear EX6920 (PPage) appears to be a 2-pack of EX6120 devices.
 * It is advertised as AC1200.


 * "U12H319 801801 REV.0 GP" is silkscreened on the board in the FCC photos.
 * "U12H319T30 LF Z142000923-00S0" is printed on a sticker adhered to the board in the FCC photos.

Internally, the board is powered by 3.3V at 2.1A.
