I use Ubuntu16.04 and my laptop model is Asus-n552vw. My wi-fi network doesn't work properly. I thought maybe the problem solved if I update my wi-fi driver. I searched for that but couldn't find how should I do it?
EDIT: My problem is very strange and stupid! If I connect to my wi-fi network at home that has 512kbps speed, I should disconnect and reconnect for every access to internet! I mean I must disconnect/reconnect to open a new site, then I must do it again for another site, or refreshing the other apps data.
But, If I use a VPN like
windscribe and connecting to it, my network works well untill I am connected to it!!!
Also when I use other network connections with 2mbps or upper speeds, it seems my network works well again!
