300Mbps Wireless N Router

Product page

The FCC ID is not valid. Additionally, there is a new FCC filing under ID: TE7WR940N

(IC ID: 8853A-WR940N) for this same model (but perhaps not the same version).

The device is the same as the TP-LINK TL-WR941ND v4.x (minus the antenna

configuration, N = integral antennas, ND = removable antennas).

The device uses an AR7240 (AR7240-AH1A) for the CPU and an AR9283.

While the device does have 3 antennas, it only has 2T2R capability (the left
and middle antennas appear to be used in a switched diversity configuration).

The default SSID is TP-LINK_XXXXXX where XXXXXX

is the last three octets of the WLAN MAC address.
