Comprei um laptop Lenovo ideapad 300 e instalei o Ubuntu 14.04 nele. A placa wifi do laptop é o dispositivo Qualcomm Atheros [168c: 0042] (rev 30).
Eu não quero atualizar para o 15.04 ou 15.10, já que estou executando um software que será executado posteriormente em servidores 14.04, portanto, quero manter meu ambiente de desenvolvimento o mais próximo possível do ambiente de tempo de execução.
Eu li que o Ndiswrapper não funciona aqui - Ndiswrapper não funciona
Encontrei então Jeremy31 responder aqui - instalar backports
Eu corri os comandos na resposta de Jeremy31 e reiniciei, mas não vi nenhuma mudança. Depois que eu corri os comandos, eu dmesg | grep ath10k não me deu nada. Os resultados de sudo modprobe ath10k_pci && dmesg | grep ath não são relevantes:
[ 0.643855] Loaded X.509 cert 'Magrathea: Glacier signing key: e09b1e7e9841e9cfef256b70ab210562dab1ef68'

[ 4855.547587] [<ffffffff81074e66>] warn_slowpath_fmt+0x46/0x50
Eu apreciarei alguma ajuda para resolver esse problema. Agradecemos antecipadamente
