Bottom of the Device

You may locate the Wi-Fi name (SSID) and password for your DAP-1900. This information is printed on the sticker on the bottom of the device. You will need this information to connect your computer or mobile device to the default network (SSID) of your DAP-1900. This information is also provided on the Quick Install Card.

Installation Wireless Installation Considerations

The DAP-1900 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 DAP-1900'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. To maximize wireless range, 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.) 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 (0.5 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 extenders, 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 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.

Hardware Setup

Plug in the DAP-1900 to a power outlet with the supplied power adapter. Verify that the Status LED is blinking orange before continuing with configuration.

Wi-Fi Mesh Setup

D-Link's Wi-Fi Mesh is a scalable solution aiming to increase the coverage and eliminate weak spots of your wireless network. Expand your Wi-Fi coverage by adding compatible D-Link access points; mix and match suitable D-Link devices according to your budget and preferences to fit any floorplan. Setup is effortless and configuration of multiple access points can be done in minutes as settings can be passed on to other access points once the first access point is configured.

Wi-Fi Mesh intelligently finds the shortest/fastest path to your router. So even if you have eight mesh nodes, you can count on Wi-Fi Mesh to stream 4K content to your device with optimal signal strength and speeds. Wi-Fi Mesh can also automatically detect malfunctioning nodes and reroute the connection to your working mesh devices.

Once the mesh network has been established, you can refer to your Wi-Fi Mesh router's configuration settings to see your mesh topology report. The DAP-1900's home screen will show the firmware information for the DAP-1900. Functions for the DAP-1900 can be configured from the uplink router's configuration page. Refer to "Home - Connected to a Wi-Fi Mesh Router" on page 25 for more information.

Setup Using the D-Link Wi-Fi App

To utilize your DAP-1900 with a mesh network via a wireless connection, select "Wirelessly" as the setup option and follow the app's instructions to complete the setup. To set up using an Ethernet cable, refer to "Setup Using an Ethernet Cable" on the next page.

Step 3

Disconnect the Ethernet cable and unplug the extender. Place the extender anywhere between your router and the area where you want expanded wireless coverage.

Connecting Wireless Clients to the Extender WPS Button

Once an uplink network has been established, you may use the DAP-1900's WPS function to add additional wireless clients to your extended network. Many wireless devices such as wireless routers, media players, printers, and cameras have a WPS button (or a software utility with WPS) that you can press to connect to the DAP-1900. Please refer to the user manual of the wireless device you want to connect to enable WPS. Follow the steps below for WPS connection setup:

Step 1 - Press the WPS button on the DAP-1900 for about 1 second. The Status LED on the device will start to blink.

Step 2 - Within 120 seconds, press the WPS button on your wireless device.

Step 3 - Allow up to 1 minute to configure. Once the LED light stops blinking and turns solid white, it indicates that the device is connected.

Troubleshooting

This chapter provides solutions to problems that might occur during the installation and operation of the DAP-1900. Read the following descriptions if you are having problems.

1. Why can't I access the web-based configuration utility?

When entering the IP address of the DAP-1900 High Performance Mesh Wi-Fi Range Extender (dlinkapxxxx.local.), your device should be in the same network as the extender.

- Make sure you have an updated Java-enabled web browser. We recommend the following:

• Internet Explorer ^ 10 or later
• Firefox® 28 or later

• Safari® 6.0 or later
  • Google Chrome™ 28 or later

• If you have an active wired LAN Ethernet connection, try temporarily unplugging the Ethernet cable from the computer you are using to eliminate possible conflicts from having two simultaneous connections on the same computer.

• Disable any Internet security software running on the computer. Software firewalls such as ZoneAlarm, BlackICE, Sygate, Norton Personal Firewall, and Windows XP firewall may block access to the configuration pages. Check the help files included with your firewall software for more information on the operation.

• Access the web management interface. Open your web browser and enter the address of your extender (http://dlinkapxxxx.local) in the address bar. This should open the login page for web management. If the DAP-1900 is connected to an uplink router, you can try accessing the web interface using a client IP address assigned from the uplink router.

• If you still cannot access the configuration, unplug the extender from the power outlet for at least 10 seconds and plug it back in. Wait about 30 seconds and try accessing the configuration. If you have multiple computers, try connecting using a different computer.

2. What can I do if I forgot my password?

If you forgot your password, you must reset your extender. Unfortunately this process will change all your settings back to the factory defaults.

To reset the extender, locate the reset button (hole) on the side panel of the unit. When the extender is powered on, use a paperclip to press the button and then release it (the Status LED should turn red). The extender will go through its reboot process (the LED remains red). Wait about 30 seconds to access the extender and you will be required to go through the initial setup again. Refer to Wireless Setup Wizard on page 15.

Appendix A - Wireless Basics

Wireless Basics

D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless connectivity within your home, business or public access wireless networks. Strictly adhering to the IEEE standard, D-Link wireless products allow you to securely and conveniently access your network. You will be able to enjoy the freedom that wireless networking delivers.

A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of wires. Wireless LANs are used increasingly in both home and office environments, and public areas such as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more efficiently. Increased mobility and the absence of cabling and other fixed infrastructure have proven to be beneficial for many users.

Wireless users can use the same applications they use on a wired network. Wireless adapters used on laptop and desktop systems support the same protocols as Ethernet adapter cards.

Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to use servers, printers or an Internet connection supplied through the wired LAN. A wireless router is a device used to provide this link.

Tips

Here are a few things to keep in mind when you are installing your DAP-1900 AC1900 High Performance Mesh Wi-Fi Range Extender.

Centralize the extender's location

For best performance, make sure you place the extender in a centralized location within your desired usage area. Try to place the extender so that there are minimal obstructions between it and the uplink router. If possible, use an elevated power outlet, so the signal can be dispersed more easily. If you have a large home or usage area, you may need several extenders in order to achieve optimal coverage.

Eliminate Interference

Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the extender. This can significantly reduce any interference that the appliances might cause since they operate on the same frequency.

Security

Don't let your neighbors or intruders connect to your wireless network. Secure your wireless network by utilizing the Wi-Fi Protected Access security feature on the extender and uplink router. Refer to the relevant sections of this manual for further details.
