9D-Link DAP-1610 User ManualSection 2 - InstallationInstallationWireless Installation ConsiderationsThe DAP-1610 lets you extend your existing wireless network’s coverage as long as it is within range of the uplink network. Keep inmind that the DAP-1610’s extension network’s range may be limited by the number, thickness and location of walls, ceilings, or otherobjects that the wireless signals must pass through. Typical ranges vary depending on the types of materials and background RF (radiofrequency) 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 aminimum - each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position yourdevices 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 (0.5 meters), at a 45-degreeangle 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) forbetter reception.3. Building materials make a difference. A solid metal door or aluminum studs may have a negative effect onrange. Try to position extenders, access points, wireless routers, and computers so that the signal passesthrough 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 RFnoise.5. If you are using 2.4 GHz cordless phones or Bluetooth (speaker, headset, printer, mice, keyboards), yourwireless connection may degrade dramatically or drop completely. Make sure your 2.4 GHz phone base is asfar away from your wireless devices as possible. The base transmits a signal even if the phone is not in use.
