Section 2 - Installation

Getting Started

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 any software is uninstalled.

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 you want to connect to

Remove Existing Installations

If you’ve installed a different manufacturer’s adapter or a different model D-Link adapter, make sure the software is uninstalled

before installing the new software. Some utilities may cause a conflict with the new software. If you plan to use multiple adapters

at different times, make sure the utilities are not set to load when your computer boots up.

To remove any old software:

Windows 10 users: Click

Start > All apps > Windows System > Control Panel > Programs > Uninstall a Program

Windows

7/8 users: Click

Start > Control Panel > Programs and Features
