Conectando-se à conexão com fio Ubuntu 14.04

0

Estou executando o Ubuntu 14.04.

Eu preciso de alguém que me diga os passos que preciso dar para corrigir este problema ...

Não é um problema da minha Internet, porque posso conectar meu outro laptop. Então, obviamente, há algo errado com meu laptop. Não faz sentido que Ele estava funcionando perfeitamente bem ontem e hoje morreu ... Eu não instalei nada.

Coisas a saber

  • Meu endereço MAC não está bloqueado (entre em contato com meu administrador de rede)

  • As conexões com fio funcionam quando cheguei em casa, mas não no trabalho. Testou a conexão com fio em outro laptop e funciona

  • A porta Ethernet não está danificada. Teste com um adaptador (mesmo resultado)

Quais são os passos que preciso dar para diagnosticar isso?
