ZyXEL AMG1202-T10A

"1105102 8951 -2.0", "Rev:1.0sp1" or something similar is silkscreened on the board.
 * The board layout is somewhat similar to the TP-LINK TD-W8951ND v3/v2.

This (plus the power adapter choice, board design, and choice of Audix as FCC testing company)
 * would obviously seem to indicate the device was manufactured by TP-LINK (Proware).

This device almost certainly uses a Ralink RT3390 chip for the wireless interface..

 * ZyXEL AMG1202-T10A • TP-LINK TD-W8951ND v3/v2
