Wi-Fi no Ubuntu Mate [RESOLVIDO]

Olá pessoal, alguém poderia me ajudar?
Eu instalei o Ubuntu Mate 16.04 no meu notebook Dell Inspiron N5010, antes eu utilizava o Xubuntu 16.04 nele e nunca tive problemas, mas quando instalei o Ubuntu Mate 16.04 o "Wi-Fi" parou de funcionar eu instalei tudo normalmente, até entrei na internet durante a instalação, porém quando iniciei o PC para utilizar o sistema não consegui entrar na internet, o icone do Wi-Fi desapareceu, já fiz tudo que eu sabia, mas n consegui resolver.
Alguém sabe como proceder nesse caso?

Obrigado
