Se spengo e riaccendo fisicamente il router non ho nessun problema,si
riavvia tranquillamente, se invece lancio il comando reload in avvio accade
quanto segue, mi va in exception all'infinito.

Anche se dopo spengo il router e lo riaccendo ho sempre lo stesso problema.
Se però stacco il cavo RJ11 il router non và in exception, ma nel momento in
cui lo rinserisco il problema salta nuovamente fuori;a questo punto non mi
resta che cancellare la configurazione e rifarla dall'inizio.
Quale può essere il problema?L'IOS che voglio mettere è compatibile con la
memoria a disposizione del mio router,ovvero 16Mb.
Ringrazio tutti per l'aiuto
