Windows Vista: Setting a Default Access Point

By default, Windows Vista will automatically switch your computer from one Wireless Access Point (WAP) to another if you move out of range, to try to keep you connected. Sometimes it can switch even if you're not moving around, and this can make you lose your connection temporarily.

If the automatic switching funuctionality is causing problems for you, you can turn this feature off:

• Open the 'Manage Wireless Networks' applet.
  
• Right-click the network profile on which you want to turn off automatic switching, and select Properties.
  
• Click the Connection tab, then uncheck the 'Connect to a more preferred network if available.' checkbox.
  
• Press the OK button
