Hei,
Eu tenho o mesmo problema que em Sem conexão wifi no Ubuntu 13.10 , mas não pode comentá-lo por causa da falta de reputação (sou novo no fórum). É por isso que abro uma nova pergunta. Eu tentei usar a solução sugerida pelo chilli555, mas recebo um erro ao executar o comando make :
make -C /lib/modules/3.13.0-35-generic/build M=/home/fe/rtl8723be modules

Pointy comentou que outro post trabalhou para ele, mas não consigo encontrá-lo.
O módulo rtl8723be é nativo no Ubuntu 14.04. Se não estiver funcionando como esperado, há algo mais errado. Tente carregá-lo e ver se há um erro ou aviso:
sudo modprobe rtl8723be
Se não houver erro aparente, verifique o log:
dmesg | grep rtl
Se você achar que está com falta de firmware, pode obtê-lo com:
sudo apt-get update
sudo apt-get install linux-firmware
Se houver outro problema, adicione as listagens dmesg à sua pergunta e prosseguiremos.
