How to view or delete preferred wireless networks ?
Under Windows Vista/7, it is sometimes necessary to change/delete preferred wireless networks (when changing the security type, for example).
The list of networks you have connected to before is accessible from:
Start button -> Control Panel -> Network and Internet -> Network and Sharing Center -> Manage wireless networks (in left pane) -> delete/edit networks as necessary
Notes: To change the order that your computer connects to networks, drag the networks up or down in the list. TOo change preferences for a network, right-click the network and choose Properties from the pull-down menu.
