N600 Wireless Dual Band Router

The BCM43236 used would appear (or would be likely) to vary..

  • At least some production units would appear to be using BCM43236B
  • The FCC docs show the device w/ BCM43236 (BCM43236KMLG, HT1127 P20, 146859 6 W)

The default SSID formats are probably NETGEARXX and NETGEARXX-5G.
