How to use

Plug the D-Link DWA-137 into an available USB port on your computer. For most modern operating systems, the adapter will be detected and configured automatically using the plug-and-play mechanism; when required, install drivers provided by the operating system or downloaded from the manufacturer’s support site. After installation, select your 2.4 GHz wireless network from the system network manager and enter the network security key to connect. Positioning the adapter in a clear line of sight relative to the wireless router can help improve signal strength.

Recommendations

Use the adapter with routers or access points operating on the 2.4 GHz band for optimal compatibility. For best performance, keep the adapter away from large metal objects and other sources of 2.4 GHz interference such as microwaves and cordless phones. If USB port space is limited, consider a short USB extension cable to improve orientation and reduce blockage of neighboring ports.
