The FCC test report lists the following additional models as covered by this FCC ID..
 * JCG JHR-N815R
 * JCG JHR-N825R
 * JCG JHR-N835R
 * JCG JHR-N845R
 * JCG JHR-N855R
 * JCG JHR-N865R
 * JCG JHR-N875R
 * JCG JHR-N885R
 * JCG JHR-N895R

Default settings are per the FCC label.
 * The default SSID pattern appears to be JCG-XXXXXX where XXXXXX is the last three octets of the BSSID (upper case letters).

Per the FCC documents (and supporting WiGLE data), the 00:E0:4B OUI is presumed to be used.
