Attaching the External Antennas
Figure 4: Attaching External Antennas
The DWR-925 requires four external antennas to function
correctly: two blade antennas for 3G/4G, and two Wi-Fi
antennas. The included antennas are interchangeable, but
third party antennas may require connection to specic ports.
1. Attach the blade antennas to the SMA connectors on the
side of the router. Turn clockwise to fasten each antenna. If
you are using third party antennas that require specic ports,
the port on the left side of the device is the“MAIN”antenna,
and the port on the right side is the“AUX” or“DRX” antenna.
2. Attach theWi-Fi antennas to the SMA connectors on the back
of the router. Turn clockwise to fasten each antenna.
3. Position the antennas where they will receive optimal signal.
Arrange them so they point upward.
