I would try the following. Stop the script network from running using
chkconfig and run NetwoirkManager and NetworkManagerDispatcher in its
place.
reboot. A applet called nm-applet will start running when you login and
put a icon in the  right corner of your upper panel. Right click on the
icon and you should see the available access point(s). Click on the one
you want. A dot circling display will occur and finally upon connection
a series of vertical bars. Along the way to connecting the first time
you will have a chance to enter the id of the access point and a WEP
password if you haven't done this. I have not set up a new access point
in awhile so I  can't describe exactly what you will see in the initial
configuration steps but it is fairly self explanatory in my memory. Ask
again if you need further clarification.
