Hardware Installation
Before You Begin
Observe the following precautions to help prevent
shutdowns, equipment failures, and personal injury:
• Install the DWR-925 in a cool and dry place. Refer to
the technical specications in the user manual for the
acceptable operating temperature and humidity ranges.
• Install the router in a site free from strong electromagnetic
sources, vibration, dust, excessive moisture, and direct
sunlight.
• Place antennas in an unobstructed area with clear mobile
signal. Avoid metal boxes, brick walls, and other dense
materials. It is recommended to use the web interface to
conrm signal strength before permanent installation.
• Visually inspect the power connector and
make sure that it is fully secure.
• Do not stack any devices on top of the router.

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 specic 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 specic 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.

Connecting Devices
After the DWR-925 has been successfully installed, the router can
be connected to the end device via the following connection
methods:
Over Ethernet
The Ethernet port can be connected to an end device. Use a
standard Category 5/5e/6 RJ-45 Ethernet cable to connect the
end device to the router. The port will auto-negotiate to the
highest possible port speed based on the connected device.
Note that the DWR-925 supports a maximum transfer speed of
100 Mbps over Ethernet.
Over Wi-Fi
You can connect to the router using the SSID and security settings
listed on the bottom of the router. If your Wi-Fi has previously
been congured, use those settings instead. The router supports
up to 802.11n speeds on the 2.4 GHz network. Maximum tranfer
speeds are dependent on network conditions.
