The Wireless Range Extender N300 lets you extend the reach of your existing wireless network, allowing you to work wirelessly
from more places in your home or office. 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 extender and other network devices to a minimum - each wall or ceiling can
reduce your adapter's range by up to 98 feet (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. At a 45-degree angle, a wall that is 0.5 meters thick (1.5 feet) appears to be
almost 1 meter (3 feet) thick. At a 2-degree angle it can appear over 14 meters (45 feet) 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 (fish tanks), mirrors, file cabinets, brick, and concrete can 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 in not in use.
