Now, let us take a look what is underneath that shiny black hood.

The 692GR is powered by a Ralink RT3883F system-on-chip (SoC) running at 500MHz. The SoC also contains a 3T3R 802.11n transceiver. The router has Macronix 8MB flash and Winbond 64MB RAM. The 5GHz band is controlled by the Ralink RT3593L. Gigabit connectivity is handled by an Atheros AR8327 5-port Gigabit controller, which also supports jumbo frames up to 9K. With the exception of the 5GHz and Gigabit Ethernet controllers, the 692GR has the same hardware as the TEW-691GR.

Underneath those RF shielding are three 2.4GHz and three 5GHz radio amplifiers. I am suprised that the 692GR uses stand-alone band antennas instead of dual-band antennas like the ones on the TEW-673GRU.


Here, we can see that the three 3dBi external 5GHz antennas connected via U.FL connectors, and three 2dBi internal 2.4GHz antennnas. There are U.FL connectors for the 2.4GHz band but upgrading them to external antennas is anything but easy.
