I have a laptop running Ubuntu 14.04, but I'm having WiFi connectivity issues. When I switch on the laptop, it can connect to WiFi with no problems, but after some time that the WiFi was on (connected or disconnected), the WiFi stops working. It shows that it is connected, but the internet connection doesn't work. If I disconnect and try to reconnect, it won't connect again to any WiFi (but Ethernet always works). I've tried to put it on airplane mode, disabling WiFi, killing wifi-manager, using a USB wireless adapter, but nothing short of rebooting works to get the WiFi back up.

I presume that the reason it works is because rebooting causes a specific service or program that is causing the issue to restart.

My question is, does anyone know how I can restart that WiFi connectivity service that is causing the issue without having to restart the whole computer?

EDIT:

The outputs of lspci -knn | grep Net -A3 are:
