Wireless Installation Considerations
The E30 lets you extend your existing wireless network's coverage as long as it is within range of the uplink network. Keep in mind
that the E30's extension network's range may be limited by the number, thickness and location of walls, ceilings, or other objects that
the wireless signals must pass through. 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 extender and other network devices to a minimum -
each wall or ceiling can reduce your adapter's range from 3-90 feet (1-30 meters). Minimize the number of walls
or ceilings your devices are positioned within.
2. Be aware of the direct line between your network devices. A wall that is 1.5 feet thick (0.5 meters) appears to
be almost 3 feet (1 meter) thick at a 45-degree angle. At a 2-degree angle, the wall appears to be over 42 feet
(14 meters) thick. Position devices for their signals to travel straight through a wall or ceiling (instead of from a
certain angle) for better signal reception.
3. Building materials make a difference. A solid metal door or aluminum studs may have a negative effect on range.
Try to position extenders, access points, wireless routers, and computers for their signal to directly pass through
drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (fish
tanks), mirrors, file 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 2.4 GHz 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 2.4 GHz phone
base is as far away from your wireless devices as possible. The base transmits a signal even if the phone is not
in use.
