Are you able to connect using other connection managers?
From my experience with ipw2200, channels above 11 are locked because of U.S
restrictions and if you live in EU you should be aware that networks can be set
to use channels 12,13. You can spot these networks but not actually connect to
them. This may be the first root of your problems.
If you are sure this is not the problem, check properly the connection
parameters like encryption method (WEP, WAP, ecc...), specifying the kind of key
you are using or the authentication method, knetworkmanager is not able to
detect these parameters automatically.

P.S.: I suggest you to edit /etc/udev/rules.d/70-persistent-net.rules to store a
different name instead of eth1, like wlan0 that's more handy.
