Feedback on the HP ProBook 440 G2 Notebook PC

Asked by Amit Chaurasia

Hi, I am using HP 440 G2 Notebook laptop with Ubuntu 14.02 OS. Since there is an issue with WI-Fi. when system get start wi-fi works for few hour after that automatically it gets disconnected and then again attempting to connect it but stuck to connect the WI-fi device OR WI-FI Router. Later it won't be connect again until you restart the system.

Also we have used different source of WiFi devices to connect with this laptop but the same issue is happens every time.

I have mentioned syslog for the same during it tried to connect device
