If you are using Vista in Network connections you will have one link like "Manage your network connections" from there you can permanently delete it.

First, go into each computer and manually delete each wireless profile. Somewhere you probably have it setup to automatically connect when it finds a connection. But You should be able to rid everything by going into (Windows > Control Panel > Internet Connections) Once you delete any profiles, then unplug your modem and router, replug them back in and proceed to use both of their reset buttons. Usually have to hold them down for 10 secs. Then all properties should be factory across the board.

Then it's just proceeding with the networking.
