EnGenius ESR1750


 * with Gigabit Ports, USB, Quantum Beam, and EnShare

Product page
 * Datasheet

"ESR1750-0.20 LFP" is silkscreened on the mainboard in the FCC photos.
 * "PAC3300-0.20 LFP 94V-0 1343" is silkscreened on the wireless module.

The FCC ID on the label on at least some of these devices appears to be A8JESR900 <??>. The newer A8JESR1750 FCC ID was issued before the end of 2013.

The filings for this FCC ID do indeed mention the ESR1750 and ESR1200 within the test report... but only 802.11n (and lower) rates seem to be tested (there is no mention of 80MHz / VHT modes) and the photos cover the ESR900 only (w/ its 3x3 11an AR9580 radio).

Additional specifications, per EnGenius's product page, follow...
 * Weight: 0.5 lbs
 * Diameter: 6.36"
 * Height: 1.64"

Default settings (including the SSID formats and the presumed used 88:DC:96 OUI) are per the FCC sample label.
