Attach the External Antennas
Figure 4: Attaching External Antennas
The DWM-312 requires two external antennas to function
correctly. The included antennas are interchangeable, but
third party antennas may require connection to specific ports.
1. Attach the antennas to the SMA connectors on the back of the
router to the ports labelled "Main" and "Aux. " Turn clockwise
to fasten the antenna.
2. Place antennas where they will receive optimal signal.
Arrange them so they point upward.
