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.

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


Upstream kernel

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)


sudo dpkg -i *.deb
sudo reboot
  • Made no difference, :( I think I should dual boot with Windows so that I can use wifi
