Minha nova instalação do Linux Mint 17.1 32bit Cinnamon Edition, instalado como o único sistema operacional em um netbook Samsung N130, perde consistentemente sua conexão de internet sem fio alguns minutos depois de se conectar, mas ainda aparece como conectado com um sinal strong. Eu tenho que reiniciar para recuperá-lo. Ele funciona bem quando conectado ao roteador pelo cabo Ethernet e nenhum dos meus outros dispositivos - telefones, etc - tem algum problema. Eu tentei instalar a versão 13 do Linux Mint (e agora reverti para 17.1), mas tem o mesmo problema.

Esta é minha primeira instalação e uso do Linux (vindo do Windows XP e instalado há dois dias), então eu não estou acostumado com isso ainda, se você precisar de mais informações, por favor, diga quais comandos eu preciso executar ou logs específicos que eu preciso olhar. Felicidades.
