(16.04) Connected to internet but not working

Question

So, everything was fine until I turned on my laptop today and then all pages gave me "Server not found". Can't even connect to the software updater. It's not a computer or internet problem because: -internet works in my windows partition (same computer) and other devices at home -tried to connect using the shared mobile internet from my phone and it didn't work either

Tried both wireless and wired

So ubuntu's internet broke just because. I tried different DNS, ips and whatnot but no luck. I'm not Linux expert so please help me. I tried to ping 8.8.8.8 in the terminal and get 64 bytes in every line, with a time averaging 39 ms and ttl=59. I have no idea what any of that means. This is quite frustrating.

EDIT: so I tried briefly to edit resolv.conf (it was blank) and added nameservers, it worked for a while, then stopped working, and now It works again. What gives? Let's see how much does it last. Leaving to the mods the best course of action regarding this thread

Are you not trying to use wifi and wired connections at same time? What is the output of your resolv.conf when your internet connection drops down? — Redbob, Aug 21 '17 at 15:57

In this case the answer is "Don't do that"

You should not edit /etc/resolv.conf by hand. In fact the default content tells you that as shown below.

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
