Sou um pouco novo no Ubuntu e tenho tentado seguir os documentos do XUbuntu, mas estou com um pouco de dificuldade.
O Network Manager não tinha nenhuma opção para se conectar ao Wifi, então presumi que isso ocorreu porque o driver não estava instalado.
O primeiro problema que tive foi digitar sudo lshw -C network e não ver REIVINDICADO / DESABILITADO / ATIVADO / NÃO RECLAMADO.
O segundo estava tentando instalar o driver para o meu computador. Verifiquei o Gerenciador de Dispositivos no Windows, vi que era um Adaptador de Rede Broadcom 802.11n e fiz o download do driver de LAN da Lenovo. Eu tentei instalar o driver usando o Windows Wireless Drivers e ele não funcionou. Me disse que não reconhecia o motorista.
Não tenho certeza do que mais tentar.

Você pode ver nessa saída que nenhum driver está listado para o chip sem fio da Broadcom (43142). Infelizmente, a Broadcom é um fabricante muito popular, que também tem um suporte pobre ao Linux, o que é totalmente culpa deles. Pesquisando seu chipset, sua única opção é tentar usar os drivers proprietários da Broadcom conhecidos como STA / WL. Isso aqui deve ajudá-lo a instalá-los .
Primeiro, remova o ndiswrapper que você usou para tentar usar o driver do Windows ...
Em terminal ...
sudo apt-get purge ndiswrapper-dkms
note: you may have to change "ndiswrapper-dkms" to something
else, depending on what you originally installed
Agora, instalamos o driver broadcom ...
sudo apt-get update
sudo apt-get install dkms broadcom-sta-dkms
reboot
Durante a reinicialização, desative secure boot na sua BIOS.
Feito!
