Overview

"EWW302-A1-BL-015" is silk-screened on the board in the FCC photos.

OEM: CyberTAN EWW302

Despite being advertised as an N600 device, the hardware is capable of AC1200 speeds and the WiFi Certification includes 802.11ac. Connecting to the 5GHz radio with both the original 4.0.0.31 (from 2019) and latest 4.0.0.37 (from 2022) firmware shows a connection rate of 866 Mb/s, same as the E5400. Unfortunately, the switch Ethernet ports are limited to 100 Mb/s.

The flash chip is a MX25L12835FM2I-10G at 16MB:
