that can accommodate a large number of computers and accessories and can separate critical...

When you set up a WLAN or access an existing WLAN, always enable security features to protect your
network from unauthorized access. The common security levels are Wi-Fi Protected Access (WPA) and
Wired Equivalent Privacy (WEP). Because wireless radio signals travel outside the network, other WLAN
devices can pick up unprotected signals and either connect to your network (uninvited) or capture
information being sent across it. However, you can take precautions to protect your WLAN:
●Use a wireless...

After the connection is made, place the mouse pointer over the network icon in the notification area, at
the far right of the taskbar, to verify the name and status of the connection.
NOTE:The functional range (how far your wireless signals travel) depends on WLAN implementation,
router manufacturer, and interference from other electronic devices or structural barriers such as walls
and floors.
More information about using a WLAN is available through the following resources:
