Before You Begin
Installation
This section will guide you through the installation process. Placement of the router is very important. Do not place the router in an enclosed area
such as a closet, cabinet, or in an attic or garage.
Observe the following precautions to help prevent shutdowns, equipment failures, and personal injury:
• Install the DWM-312W in a cool and dry place. Refer to the technical specifications 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.
