ZyXEL AMG1202-T10A

"11051028951--2.0", "Rev:1.0sp1" or something similar is silkscreened on the board. This (plus the power adapter choice, board design, and choice of Audix as the FCC testing company) would obviously seem to indicate the device was manufactured by TP-LINK. The board layout is somewhat similar to the TP-LINK TD-W8951ND v4.

This device almost certainly uses a Ralink chip for the wireless interface.. probably RT5390.

The FCC test report also lists the following models as covered by this FCC ID...
 * AMG1202-T10A
 * P660HN Lite EE
 * P-660HN-T1S
