It tries then to reassociate for 10 times although it is not dealing with the same network. A patch that add a key mgmt mismatch flag when trying to connect to a WPA network with WEP secutiry settings would prevent such an issue. Please refer to the attached patch.

This is the way a WEP station that is not aware of WPA/WPA2 would behave
and that used to be the expected wpa_supplicant behavior with WEP
configuration. In other words, this was not really an issue but the
designed functionality.. Anyway, this was changed recently with this
