Eccomi qua.
Ho fatto diligentemente tutti i compiti per casa che mi ha assegnato Argos. Sono in Mandriva 2011. Ecco i risultati:

Immediatamente dopo la disconnessione, il comando

Aggiungo un altro particolare: la prima connessione, quella che parte all'avvio, è solitamente quella che regge di più. Dopo la prima disconnessione, le disconnessioni successive sono più frequenti.
Per riconnettermi devo ogni volta disattivare e riattivare la rete senza fili.
Salutoni e grazie ancora
