I recently installed Ubuntu 16.04 on my laptop. Things all going smooth but one day I cannot access any webpages on the same network.

Then I try installing 18.04 and connected on the same wifi network and it worked! Then I tried installing 16.04 again to see if it will work now but still no good.

I tried pinging router IP address and get response. Ping also get response, but pinging google.com is no good.

Is there any code that I can use of you guys to see my network configuration? 18.04 is no good for my laptop since it's a really old laptop.
