Como resolver isso?

Seguindo o conselho de Hennes, com sudo

Eu deveria apenas adicionar meu lspci -vvnn | grep -A 9 Network

Você pode instalar o pacote bcmwl-kernel-source a partir da pasta restrita sob ../pool/restricted/b/bcmwl na mídia de instalação do Ubuntu.

Para descobrir o seu kernel atual, use o comando:

 uname -r

Para descobrir quais pacotes de cabeçalhos linux você instalou, use o comando:

dpkg --get-selections | grep headers

Os sistemas instalados a partir do CDROM podem adicionar o CD de instalação como fonte de pacotes e instalar o bcmwl-kernel-source usando o apt-get. No entanto, se você quiser fazer isso manualmente, as instruções são as seguintes:

Navegue na mídia de instalação e instale os pacotes listados abaixo clicando duas vezes OU instale os pacotes consecutivamente de um Terminal (nos comandos abaixo, a mídia de instalação é montada em / cdrom, mas a sua talvez seja diferente):

1) / pool / main / d / dkms

  cd /cdrom/pool/main/d/dkms
  sudo dpkg -i dkms*

2) / pool / main / p / patch

  cd /cdrom/pool/main/p/patch
  sudo dpkg -i patch*

3) / pool / main / f / fakeroot

  cd /cdrom/pool/main/f/fakeroot
  sudo dpkg -i fakeroot*

4) / pool / restrito / b / bcmwl

 cd /cdrom/pool/restricted/b/bcmwl
 sudo dpkg -i bcmwl-kernel-source*

Instale o pacote b43-fwcutter. Isso geralmente está localizado na mídia de instalação do Ubuntu em / cdrom / pool / main / b / b43-fwcutter / Clique duas vezes no pacote para instalar ou, em um terminal, execute os seguintes comandos:

 cd /cdrom/pool/main/b/b43-fwcutter/
 sudo dpkg -i b43-fwcutter* 

 sudo modprobe -r b43 bcma

Reinicie
