[resolvido] [duplicado] Sou um utilizador do Ubuntu 15.04 vivid 64 bits Eu tenho tantos problemas desde 15.04 com o meu wifi, tão chato :( A conexão é instável, perdendo o pacote, perdendo a conexão após a suspensão automática, etc ... Na inicialização, o WiFi está correto, mas depois de algumas vezes (irregular) ele foi embora. Freqüentemente, a barra de status me diz "Wifi is not ready" ou "wifi is deactivated" (nenhum botão físico ...)
Por favor, alguma ajuda será ótima Algumas informações abaixo:

Eu coloquei o ideapad_laptop na lista negra em /etc/modprobe.d/blacklist.conf
Eu não tenho um /etc/modprobe.d/iwlmvm.conf , pois quero usar o Wifi 11N ...
Estou usando /lib/firmware/iwlwifi-7260-13.ucode (enganando o sistema operacional renomeá-lo .10)
