Na wstępie pragnę zaznaczyć, że przejrzałem forum i wiem, że temat ten był już kilka razy poruszany. Niestety nie pomogło mi to w rozwiązaniu mojego problemu. Zacznę od początku. Debiana (w wersji testowej) używam od kilku miesięcy i nigdy nie miałem żadnych problemów z internetem. Problem zaczął się gdy po ostatniej aktualizacji oprogramowania (safe-upgrade) i przeładowaniu komputera, straciłem dostęp do internetu. Przejrzałem pliki konfiguracyjne. Plik resolv.conf był wyczyszczony. Zawierał tylko informację:
