Wifi O Intel Centrino N-2230 não funciona no Dell Inspiron 17r SE no Ubuntu 14.04 LTS

2

Eu tive que reinstalar meu sistema Ubuntu porque ele não estava funcionando corretamente, então eu fiz com uma instalação USB e mantive meu antigo / home. O Wifi estava funcionando bem no meu sistema 14.10 e até mesmo no Live CD, mas agora cheguei a 14.04 LTS e não está funcionando. Quais são os pacotes e eu preciso baixar para ter meu back wifi funcionando?

O módulo não está carregando, então gksudo gedit /etc/modprobe.d/iwlwifi.conf Exclua o que está lá e adicione %código% Salve, saia do programa e remove iwlwifi \ (/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \ && /sbin/modprobe -r mac80211 options iwlwifi 11n_disable=8 ou reinicie e veja se funciona
