This is annoying, my internet connection drops after a few minutes and I have to restart my Lenovo G40-70 because restarting the network manager doesn't work.I also tried the solutions from related solved questions but none of them fixed the problem.

You can install a better driver

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms linux-firmware

And reboot
