I updated my Lubuntu 16.04 to 17.04 and it is now not connecting to my WiFi. It is detecting the signal, but doesn't want to connect. I deleted the connection and then tried to reconnect to the network but it has not helped.

Any ideas?

See below for info:

  • Welcome to AskUbuntu! Could you please run the network diagnostics and [edit] your question to include a link to the result? I know it may seem a bit overwhelming for a novice but your info so far is a bit vague and the diagnostics will likely cover all options that may cause your issue. Thanks. – David Foerster Apr 15 '17 at 08:18
  • Thank you @DavidFoerster. I ran the script and edited the question to the result. – Jay P Apr 16 '17 at 17:47
  • Sorry to tell you, yesterday I faced the same problem. Couldn't find a solution I installed back my 16.04. There are 3 reported solution you could find. But none of them worked for me. 1)DNS 2)MAC ID 3)Download and install the driver separate. Just search it. – Sreeraj Chundayil Apr 16 '17 at 18:22
  • This worked for me after installing Ubuntu 17.04 https://askubuntu.com/questions/902992/ubuntu-gnome-17-04-wi-fi-not-working-mac-address-keeps-changing – dipu Apr 16 '17 at 18:48
  • For some reason the rfkill command is unavailable on your system. Could you please reinstall it (sudo apt-get install --reinstall rfkill) and [edit] your question to include the output of sudo rfkill list? If you can't get internet via Ethernet and don't know how to install packages without an internet connection you're welcome to ask for help. Thanks. – David Foerster Apr 17 '17 at 19:53
  • I had the same problem after upgrade from 16.10 and tried the solution mentioned here (edit Networkmanager.conf) and many others. None did help. But then I just deleted the wifi networks and connected again and everything worked! Eg this was not a problem of network manager itself, but the connections did not work (visually all setting were the same, so I have no idea what caused it). – MF.OX May 23 '17 at 12:57

Miraculously, a user from omgubuntu.co.uk had written a comment in one of their articles announcing the release of 17.04 that fixed this issue. The comment is as follows:

wifi and networkmanager

The new NetworkManager release 1.4.0 adds new features to change the current MAC address of your Ethernet or Wi-Fi card (spoofing/cloning). As a debian "sid" user i understand that being on bleeding edge, sometimes new features and configs can be Incompatible with my machine hardware!!! Now being a ubuntu user i can see that ubuntu is losing his "user friendly" name and no more care for desktop users! This was an unacceptable default config on Ubuntu's best days! Ubuntu haters and criticists must be happy now!

fix it

edit the /etc/NetworkManager/NetworkManager.conf file

And add:

[device] wifi.scan-rand-mac-address=no

Restart the networkmanager service and use your wireless connection :)"

I found that applying his fix by opening a Terminal and typing "sudo gedit /etc/NetworkManager/NetworkManager.conf", adding the text he described, then rebooting my machine fixed the issue.

That being said, this default behavior is still a major bug and breaks functionality of wi-fi hardware for users, and definitely needs to be looked at. Thanks for your time!

  • Yes this will fix the issue. But before doing these steps delete previously created wifi connections. Otherwise this won't fix the problem. Because for me once I deleted it only get it working. – GPrathap Aug 13 '17 at 15:22
