Não é possível conectar-se à Internet mesmo que eu tenha conseguido durante a instalação (Debian)

1

Como eu disse no título, tenho dificuldades em me conectar à Internet. Durante a instalação do Debian 7.1 eu forneci o assistente com o arquivo htc_9271.fw quando ele perguntou. Depois disso, conectei-me ao servidor ftp e baixei alguns arquivos adicionais. Após a instalação, o meu adaptador de cartões TP-LINK WN722N desligou e parece que não consigo funcionar. Nas opções de rede, diz: wireless é desativado pelo switch de hardware. Não há nenhuma opção neste cartão e ele deve estar ativado por padrão. Também funciona perfeitamente no Windows 7 (depois de usar drivers). Antes de instalar o Debian eu tentei Ubuntu e também não funcionou. Eu sou um novato, então não tenho certeza se lhe forneci informações suficientes. Sinta-se à vontade para pedir mais. Agradeço muito sua ajuda, pois preciso ter minha configuração de distribuição do UNIX para palestras / laboratórios de ciência da computação.

Aqui está uma saída do terminal:
