Conecte-se à internet por fio e execute
sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms
Isso instalará um driver melhor. Teste após a reinicialização.
Estou enfrentando frequentes desconexões WIFI e nenhuma das sugestões que encontrei está funcionando:
