I've seen this question and tried the answer at the bottom of the page yesterday and it seemed to work. But then I woke up today and had the same DNS_PROBE_FINISHED_BAD_CONFIG error for like over an hour. So then I tried that solution at the bottom again and it seems to have worked but just in case I created an account and am making this question. I also tried the answer with 26 likes but ran into a problem. I pasted sudo rm /etc/resolv.conf to my terminal and after typing in my password nothing happened.

EDIT: The error happened again as I was trying to post this. I am now using a wired connection.

When I pasted ls /run/resolvconf/interface/ in the terminal I got NetworkManager.

EDIT from comments: I have a modem from ubee, it's DDW365

Everything from " localhost" to "ff02::2 ip6-allrouters" was what was within my hosts file.   localhost   aaron-Aspire-One-721

#The following lines are desirable for IPv6 capable hosts

::1     ip6-localhost ip6-loopback

fe00::0 ip6-localnet

ff00::0 ip6-mcastprefix

ff02::1 ip6-allnodes

ff02::2 ip6-allrouters

This is from my host.conf file:

 # The "order" line is only used by old versions of the C library.
    order hosts,bind
    multi on

None of my DNS match the DNS here.

  • It says Automatic as method. The Address box is also blanked out. Sep 27 '16 at 22:18
  • And I have a hosts file and a host.conf file. So I misread when I said I had two earlier. Sep 27 '16 at 22:25


sudo dhclient -r interfacename
sudo dhclient interfacename

where interfacename is yours (mine is eth0)

This will release and renew your Ip address.

If this doesn't help, The COX DNS servers you are using may be overloaded. This is especially likely if this is an intermittent problem.

Google Public DNS operates recursive name servers for public use at the following IP addresses: and for IPv4 service, as well as 2001:4860:4860::8888 and 2001:4860:4860::8844, for IPv6 access. The addresses are mapped to the nearest operational server by anycast routing. I suggest you try those and see if you get better results.

I've found to be very responsive. Open Network Connections and edit your entries as shown below. Then Click Save. This should resolve the issue.


  • I already have that stuff saved to my hosts file. I'll enter that command in the terminal. Sep 27 '16 at 22:20
  • I did everthing you asked me. Sep 28 '16 at 2:31
  • How do I find my network interface name? I just noticed that you edited your post. Also, this problem is intermittent. I've never had this happen before until now. Sep 28 '16 at 16:23
  • nmcli device show will give details on both the wired and wireless and it will be clear which is which. See my answer in regards to intermittent DNS problems. (I.E. Change DNS settings)

  • This is what I get when I type that. i.imgur.com/LTY1l0b.png I used the text with DDW365 in it but it was apparently too long. Sep 28 '16 at 17:00
