Salve, negli ultimi due giorni il comportamento del mio modem router è strano e la navigazione è di una lentezza esasperante.
Per strano intendo che mi fa entrare nella pagina di configurazione solo dopo averlo resettato e solo da internet explorer (normalmente uso firefox e non ho mai avuto problemi a configurarlo all'indirizzo 192.168.0.1). E' un Sitecom 150 N (modello wl346) e mi ci collego normalmente wireless.
Le varie schede del modem oggi si aprono lentamente e dal log risulta uno smurf.

Sono sotto attacco di qualche figlio di buona donna?
Come mi devo difendere?

Salve! Resetta il router, accedi alle impostazioni da FireFox, disattiva il wireless, metti la password d'ingresso al router, salva ed esci.

Prova a navigare.

Come ho detto, da firefox NON riesco ad entrare.
Dopo aver inserito username e password continua ad apparire la finestra "autenticazione richiesta inserire nome utente e password".
