Estou usando um Lenovo T470 recém-adquirido com o Realtrek Wireless no Ubuntu 16.04 LTS. Depois de conselho do Jeremy31 , eu instalei o driver com -
sudo apt-get install git build-essential
git clone https://github.com/rtlwifi-linux/rtlwifi-next.git
cd rtlwifi-next
make
sudo make install
No entanto, o funcionamento sem fio só funciona nos primeiros minutos após a reinicialização. Mais tarde é desativado de alguma forma.
sudo lshw -C network

Eu verifiquei que não está bloqueado.

Existe alguma sugestão que eu deva investigar? A propósito, eu tenho o PrivateInternetAccess instalado, mas o killswitch está desativado.
