Recently I came using Ubuntu on my Notebook normally, and out of nowhere I could not access anything else in Firefox, nor check for updates. Could someone help me? I am running Ubuntu 17.10 on a Dell Inspiron 5558! Screenshot from the WiFi icon

BTW, there is the output of ip link and ip route:

gabriel@INSPIRON-5558:~$ ip link 
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

  • Please [edit] your quesiton and include the output of ip link and ip route when connected to a WiFi. You can run the commands from a terminal. – vidarlo Dec 26 '17 at 18:34
  • @vidarlo I already added to the question. – Gabriel Furtado Dec 26 '17 at 18:50
  • Shows that the connection is up. What happens if you try respectively ping -c 4 google.com and ping -c 4 8.8.8.8? Does one of the ping commands work? – vidarlo Dec 26 '17 at 18:56
  • @vidarlo It shows that google.com is an unknown name or service, and 8.8.8.8 shows 4 packets transmitted, 4 received, 0% packet loss, time 3004ms rtt min/AVG/max/mdex = 129.918/130.564/132.226/0.996 ms – Gabriel Furtado Dec 26 '17 at 19:02
  • Have a look at this Q&A. It's a DNS problem. I don't know the details of how 17.10 does DNS, but that Q&A should help you I believe. Try for instance dpkg-reconfigure resolvconf first. – vidarlo Dec 26 '17 at 19:11
  • @vidarlo I tried this instance and didn't worked, it shows a error of conflicting actions. I'll take a look on this other Q&A. BTW, thanks for helping! – Gabriel Furtado Dec 26 '17 at 19:17

I managed to fix the error, was basically install resolvconf again and restart the computer. That means this problem has been solved!

How I did this:

  1. Downloaded the .deb file of resolvconf. Link: http://archive.ubuntu.com/ubuntu/pool/universe/r/resolvconf/resolvconf_1.79ubuntu8_all.deb
  2. Installed the .deb file of resolvconf on terminal. Command: dpkg -i <file location>
  3. Started resolvconf with systemctl. Command: systemctl start resolvconf
  4. Rebooted the computer.
  5. WiFi is back!

  • Snyver, you can accept your very own answer as well to mark the issue as solved (instead of adding (SOLVED) to the question's title). But I'm not sure whether that works with your current reputation. But in general it works and is not considered a bad idea. – PerlDuck Dec 26 '17 at 20:30
  • @PerlDuck OK, I'll remove it. – Gabriel Furtado Dec 26 '17 at 22:24
