Per the FCC photos...

  • "P/N: 363300045452 REV 04" (this is almost certainly mostly wrong)
appears to be silkscreened on the main board.
  • "PN:382208100202-10" is silkscreened on the RT3883 module:
WiSoC: Ralink RT3883 @500 MHz 3T3R (iNIC)
RAM: EtronTech EM639165TS-6G (16MB)
  • The Intel SoC is marked with..
i(M)(C)07
W222TH52
SLHCV (E1)
SNCE2500GU

The Coaxial portion is using a MxL (MaxLinear) MXL261.

The device may use a B8:9B:C9 (SMC Networks) OUI.

The default credentials in this entry are from the FCC manual

and may not be fully accurate.
