Zrywa połączenie z internetem

[Faz]

Witam wszystkich linuxiarzy.

Mam problem, który nie potrafię rozwiązać, dlatego postanowiłem poprosić Was o pomoc. Kupiłem laptopa Dell Vostro 15 3000 Series, z systemem Ubuntu 14.04 LTS, w październiku i od początku miałem problem ze zrywaniem połączenia wymagającego kabla (ethernet i dsl), wifi działa poprawnie. Czasami działa 20 min, 30 min, 1h (różnie) i zrywa (tak jakby zapominało hasła w połączeniu ethernet, w dsl nie wiem). Aby połączenie ethernet działało ponownie muszę wyłączyć i włączyć laptop, a dsl  wyłożyć i włożyć kabel sieciowy. Prawdopodobnie jakiś problem z kartą sieciową, sterownikami tak sądzę. Byłby wdzięczny za poprowadzenie mnie przez czynności jakie trzeba wykonać, ponieważ słabo się znam na tym syystemie.
