Section 2 - Installation

Installation

This section will walk you through the installation process. If you have a built-in wireless adapter, please disable it in Device Manager before installing your D-Link adapter. Also, if you have previously installed another wireless adapter, please make sure its software is uninstalled.

Getting Started

Before installing your new D-Link wireless adapter, please verify the following:
• Remove any previous installations of wireless adapters
• Disable any built-in wireless adapters
• Verify the settings such as the SSID and security settings of the network(s) you want to connect to

Remove Existing Installations

If you’ve installed a dierent manufacturer’s adapter or a dierent model D-Link adapter, make sure the software is uninstalled before installing the new software. Some utilities may cause a conict with the new software. If you plan to use multiple adapters at dierent times, make sure the utilities are not set to load when your computer boots up. Windows® XP users may use the built-in wireless utility for all adapters.
To remove any old software: Windows® 7 users: Click Start > Control Panel > Programs and Features. Windows® XP/Vista® users: Click Start > Control Panel > Add or Remove Programs.

Disable Other Wireless Adapters

Most newer laptops may include a built-in wireless adapter. To prevent any conicts with the D-Link wireless adapter, it is recommended to disable the wireless adapter (as well as any unused Ethernet adapters).
From the desktop, right-click on the My Computer icon and select Properties.
Click the Hardware tab and then click Device Manager. Scroll down the list and click the + sign to the left of Network Adapters.
Right-click the adapter you would like to disable and select Disable.

Wireless Installation Considerations

The D-Link wireless adapter lets you access your network using a wireless connection from virtually anywhere within the operating range of your wireless network. Keep in mind 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 adapter 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 dierence. A solid metal door or aluminum studs may have a negative eect 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 2.4 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.

Connecting to a Wireless Network

Using Windows® 8

It is recommended to enable wireless security (WPA/WPA2) on your wireless router or access point before conguring your wireless adapter. If you are joining an existing network, you will need to know the security key (Wi-Fi password) being used.
To join an existing network, locate the wireless network icon in the taskbar, next to the time display.
Wireless Icon
Clicking on this icon will display a list of wireless networks which are within connecting proximity of your computer. Select the desired network by clicking on the network name.

Section 3 - Connecting to a Wireless Network
You will then be prompted to enter the network security key (Wi-Fi password) for the wireless network. Enter the password into the box and click Next.
If you wish to use Wi-Fi Protected Setup (WPS) to connect to the router, you can also press the WPS button on your router at this point to enable the WPS function.
When you have established a successful connection to a wireless network, the word Connected will appear next to the name of the network to which you are connected.
