I have a modem that distributes Wi-Fi, and there is a laptop with ubuntu 14.04.

Then there are 3 situations:

1 - I connect to the Internet via Wi-Fi, Skype works for me, I download torrents, I can google, but other than that I cannot go to any other site, I write an error DNS_PROBE_FINISHED_BAD_CONFIG .

2 - turn off Wi-Fi, connect to the router through the wire, as a result, there is no Internet at all, error ERR_NETWORK_CHANGED .

3 - I connect to the router via Wi-Fi and insert the cord, as a result, the Internet works.

I want the first and second methods to work too, tell me what the problem is, I suspect that something with the dns settings on the computer ...

It is worth adding that from the phone I connect via Wi-Fi and the Internet works on it.

  • And why do you need DNS on your computer? Did you put a DNS server? - Hermann Zheboldov 1:51 pm
  • No, I did not put anything, but in the error it is written about the dns configuration error, did I understand correctly? - fortunado
  • Well, then take a look at the network connection settings that you have written about the DNS. I don’t remember from memory, I’ll get to my house - I’ll write in more detail - Hermann Zheboldov
  • Primary DNS is written in the Connection Information: 192.168.1.1, dns is not mentioned anywhere else in the connection or the connection settings, if I understood you correctly) - fortunado
  • 192.168.1.1 - is this a router? - Hermann Zheboldov

Try the following:

Run the command

 sudo resolvconf -u

If the answer type is

 /etc/resolvconf/update.d/libc: Warning: /etc/resolv.conf is not a symbolic link to /run/resolvconf/resolv.conf`

then execute the following commands:

 sudo rm /etc/resolv.conf sudo ln -s ../run/resolvconf/resolv.conf /etc/resolv.conf sudo resolvconf -u
  • I have no errors from the sudo resolvconf -u command and nothing has changed or do I need to restart the computer? I just can not reboot now. - fortunado
