Ho da circa un mese una ADSL domestica con Alice. Fino a ieri nessun problema, appena configurato il 1721 (con una conf. ovviamente presa qui

Ieri c'e' stata una mancanza di energia elettrica per circa mezz'ora. Quando la corrente e' tornata, il router e' ripartito, sembra che sia tutto OK ma non navigo.
Siccome ho navigato fino a ieri, tenderei ad escludere un problema di configurazione, per cui evito di postarla.
Sono abbastanza inesperto di dialer, per cui non so neanche come fare troubleshooting. La spia della portante (CD) e' accesa, l'interfaccia ATM e' UP.

il problema pero' che non riesco a pingare tale IP, quindi la cosa mi sembra strana.
Cos'altro potrei verificare?
