Ubuntu 8.04 - Wicd vede tutti i miei router wireless ma non si connette a nessuno! -

[dacri]

Ciao a tutti, questo è il mio problema: uso Wicd x connettermi wireless a diversi router..il mio a casa, quello della mia ragazza, e quello dei genitori.
Il problema è che Wicd nella lista gli vede ma quando clicco su connetti lui scrive: obtaining IP address, mentre cerca, e alla fine ritorna alla schermata con la lista dei router senza essersi collegato a quello da me prescelto.
In questo momento sto cercando di collegarmi al router speedtouch della tiscali..
questo il mio ifconfig:
