Olá, estou utilizando o Ubuntu 11.04 pela primeira vez e estou encontrando o seguinte problema: estou conseguindo detectar todas as redes disponíveis, mas quando tento conectar, após pedir a chave, o ícone do wireless fica piscando e a conexão não é estabelecida. Meu note é um aspire 5050-3233. Estou mandando um ctrl-v dos comandos:
sudo lshw -C network
iwconfig
ifconfig -a
nm-tool
Seguem os comandos e, desde já, obrigado.
