Site Survey
A site survey utility provided with the WebSTAR DPW939 USB Wireless LAN
Adapter analyzes the installation environment and provides users with
recommendations for equipment and its placement. The optimum placement
differs depending on the device design and specifications. Refer to Locating
Available Wireless Networks, later in this guide for detailed procedures on
using the site survey utility.
Roaming Information
Use the Mobile Manager utility to set up automatic roaming and network
reconfiguration between different locations. Roaming allows you to change your
location and still maintain communication between other devices within range
that have compatible wireless PC cards installed. Roaming among different
access points is controlled automatically to maintain the wireless connectivity at
all times.
Tips on Roaming
• The DPW939 can only roam between APs of the same type.
• All computers with WebSTAR WLAN cards must have the same SSID as the
access points to enable roaming.
• If encryption is enabled, all wireless clients must use the same encryption to
establish connection.
• We strongly recommended that you perform a site survey using the
WebSTAR DPW939 USB Wireless LAN Adapter utility to determine the best
location for each wireless device.
