Hardware Overview
Switching Between 3G Modem Mode and Wi-Fi Router Mode
The DIR-457U features a hardware switch that enables users to switch between 3G Modem mode and Wi-Fi Router
mode.
When the DIR-457U is in 3G modem mode, the device connected via the included USB cable maintains a direct 3G
Internet connection. Use the Connection Manager to congure the 3G connection sharing for additional wireless devices
when the DIR-457U is changed to Wi-Fi Router mode.
In Wi-Fi Router mode, the DIR-457U can share
the 3G Internet connection with multiple Wi-Fi
clients. Use DIR-457U to connect notebooks,

• Battery power lasts up to 4 hours in standby status.
• Battery life depends on network, signal strength, temperature, features, and accessories.
• New batteries or batteries not used for an extended period may take longer to fully charge.
• Always charge the battery at room temperature.
• The battery may perform best after several full cycles of charging and discharging.
• Store the battery uncharged in a cool, dark, dry place.
• Never expose batteries to temperatures below –10°C (14°F) or above 45°C (113°F).
• Leaving the battery in a hot vehicle may degrade long-term performance of Li-Ion batteries..
• It is normal for batteries to gradually wear down and require longer charging times.

Section 2 - Installation
When using the DIR-457U in Wi-Fi router mode, placement of the device is very important. Do not place the device in
an enclosed area such as a closet, cabinet, or in the attic or garage. Please install the device considering the following
points:
Installation
The D-Link DIR-457U in Wi-Fi router mode lets you access your network using a wireless connection from virtually anywhere within the
operating range of your wireless network. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects
that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background
RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines:
1. Keep the number of walls and ceilings between the D-Link router and other network devices to a minimum - each wall or
ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls
or ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a
45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters)
thick! Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better
reception.
3. Building Materials make a difference. A solid metal door or aluminum studs may have a negative effect on range. Try
to position access points, wireless routers, and computers so that the signal passes through drywall or open doorways.
Materials and objects such as glass, steel, metal, walls with insulation, water (sh tanks), mirrors, le cabinets, brick, and
concrete will degrade your wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.
5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security
systems), your wireless connection may degrade dramatically or drop completely. Make sure your 2.4GHz phone base
is as far away from your wireless devices as possible. The base transmits a signal even if the phone in not in use.
