EnGenius ESR-9750G

The datasheet says the device has 8MB of Flash and 16MB of RAM. The internal photos (and user submitted photos on the DD-WRT forums below) depict the device with a Macronix MX29LV320CTTC-70G (32Mb, 4MB) chip. The device also has internal U.FL connectors in the FCC internal photos.. but the pigtails are directly soldered in the below photos on the DD-WRT forums.
