Recently I installed Ubuntu 16.04 on my vaio vpccb17fx with Intel Centrino Wireless N1000. Unfortunately my signal strength is very weak, it keeps disconnecting and actually I can't use Wifi! I don't know what to do as I'm new to Linux. I would be very grateful for someone who could help me (and maybe others have the same problem) Thanks.

I tried this, but made no difference, so reverted that.– Hamed.YMay 7, 2016 at 14:04

WIFI regulatory domain not set
Set the WIFI country code for the Kernels current regulatory domain if it isn't set.
iw reg get
To set it
sudo nano /etc/default/crda REGDOMAIN=<ISOCODE>
Try the latest upstream kernel. I saw WIFI bug-reports that were fixed with a new kernel, so it's worth a try. It also fixed mine. Read more about upstream kernels here.
Download and install the packages that corresponds to your architecture (e.g. AMD64, kernel 4.6-rc7-wily)
