1. Access your wireless network Properties window. For example, in 
Windows XP you would click 
Start > Control Panel > Network 
and Internet Connections
. Then click the Network 
Connections
 icon. You see a screen similar to this:

software that came with 
your access point. 
Right-click and select Status
