internet wifi po pewnym czasie gubi po

[orzechus]

Mam nowo zainstalowanego Debiana Jessie z Xfce. Problem polega na tym, że załaduje się parę stron w przeglądarce i koniec, brak internetu. W konsoli też stoi. Przeglądałem trochę internetu żeby to naprawić, ale nie udało mi się. Proszę o pomoc. Oto garść informacji.
