Wikidevi Notes[edit]

Product page (US)

Per this DD-WRT forums post, the shields are soldered on preventing removal for chip identification. The wireless chip appears to be an AR9381 or AR9384.. as the AR9384 does not seem to exist, it can be assumed the device uses AR9381. This post on wifi.com.cn says the device uses AR7242, AR8316, AR9381, and has 32MB + 64MB of Flash and RAM.. respectively. The AR8316 is visible in the FCC photos.

DD-WRT router info screenshot confirming AR7242, the default FW is DD-WRT

The FCC photos show the device with an MAC sticker with an OUI of 4C:E6:76.

"2976374002" is silkscreened on the board in the FCC photos.
