Tenho internet no dito telemóvel, LG E610.
Ao ligar por cabo o telemóvel à porta USB, posso escolher no telemóvel a opção partilhar internet.
O problema é que a partir do PC portátil, um Acer Aspire E1-570G com o Ubuntu 14-04 instalado não consigo aceder à internet.
Estou a aceder criando um hotspot wireless no telemóvel.
Povavelmente está-me a escapar algo...
Obrigado

Execute os comandos abaixo no seu Ubuntu, com o hotspot ativo, e cole o resultado aqui.
sudo lshw -C network
iwconfig
ifconfig -a
nm-tool
rfkill list wifi

Qual destas é a rede do seu portátil?
-
Ao ligar por cabo o telemóvel à porta USB, posso escolher no telemóvel a opção partilhar internet.
Hmmm. Perdão, eu tinha entendido que vc estava querendo conectar-se ao telemóvel via wireless.
Qual é a marca/modelo do seu portátil?
Execute também o comando abaixo em seu portátil, com o telemóvel conectado.
lsusb
PS: Desculpe a confusão, mas é pq do lado de cá do Atlântico chamamos o portátil de notebook ou só note, e o telemóvel de celular ou smartphone. Até pq tanto um quanto o outro são portáteis...

Amigo,
Abra o network manager (icone de rede perto do relogio em cima na barra)
Crie uma nova conexão de rede escolhendo como interface USB0 com dhcp automatico
Conecte a rede pelo telemovel
Experimente fazer e verificar se funciona

Sim, aparece.

Hmmmmmmmm. Quer fazer uma tentativa? Edite (como root) o arquivo /etc/network/interfaces e adicione as linhas abaixo.
allow-hotplug usb0
auto usb0
iface usb0 inet dhcp
Depois tente ativar a conexão, com o comando abaixo:
sudo ifup usb0

Faça o teste de desconectar seu celular e conectar de novo, veja se conecta automaticamente a internet.

Parece-me que tenho que fazer
sudo ifdown usb0
e depois voltar a fazer
sudo ifup usb0
