Answer 1

Instale outro driver dessa maneira

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtl8192cu-dkms

A nova versão deste driver deve melhorar as coisas. Se isso não ajudar, eu tenho outro driver dkms neste PPA que deve funcionar com certeza, mas é mais antigo.
