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.
