    Edison Wifi does not connect

    ForumMigrationAdmin

      Hi folks,

      I am trying to set up wifi with my intel Edison, but it fails all the time. Just to make sure, I first type

      root@EdisonByChris:~# rfkill unblock all
      

       

      Then I type

      root@EdisonByChris:~# configure_edison --wifi
      

       

      and get

      Failed to connect to non-global ctrl_ifname: (null)  error: No such file or directory
      Failed to connect to non-global ctrl_ifname: (null)  error: No such file or directory
      
      


      and no wireless networks are listed. However, some are definitively available. So I tried the following:

      root@EdisonByChris:~# systemctl start wpa_supplicant
      root@EdisonByChris:~# wpa_cli
      

       

      but then I get:


      Interactive mode
      
      Could not connect to wpa_supplicant: (null) - re-trying
      


      Does anybody know how to diagnose/fix this?

      Thanks!

          Did you update the Edison first? (copy the latest Edison image and do reboot ota)

            In fact I did, but I am not convinced it worked. There was no obvious error message, but it did not change the host name, so I suppose something went wrong. Anyway, this version is now installed:


            root@EdisonByChris:~# uname -r
            3.10.17-poky-edison+
            


            Would that be the current version? If not, how can I see what went wrong with the update?

            Thank you!

              Okay, never mind. For some reason upon retry the update worked now and so does wifi!

              Thanks a lot!

                Good to hear that it is working now.

                Just for reference, this is how you get the current version:

                configure_edison --version

                  PLEASE HELP, I am really stuck:

                   

                  I am having the exact same problem, but nothing I do seems to clear it up.

                   

                  Yes, I grabbed the latest version and updated it and ran "reboot ota".

                   

                  As per other threads on this topic, I've deleted various log files and all /var/log/journal files. To no avail.

                   

                  Here's the version I'm running:  "3.10.17-poky-edison+"

                   

                  BTW:  I find it very curious that many in this forum refer to commands like "configure_edison --version", "configure_edison --latest" and "configure_edison --upgrade" since NONE of these three commands are supported by the configure_edison script on my Edison system.

                   

                  Whenever I enter any of these three flags "configure_edison", the script promptly shows me it's Help screen which makes NO REFERENCE to any flags like --upgrade, --latest, or --version.

                   

                  The only flags that my configure_edison supports are --name, --password, --changeName, --changePassword, --wifi and --server.

                   

                  How is it that others seem to have a different version of configure_edison on their system(s)?

                   

                  Thank you.

                    Ok, Hi again, all -

                     

                    For those of you who did not get any relief from the prior answers to this thread, here is the solution / steps that fixed MY SITUATION that resulted in precisely the same symptoms:

                     

                    FAULT:  My /etc/wpa_supplicant/wpa_supplicant.conf file had become bloated / corrupted with 250 lines and approximately 20 connection records. They were, all but 2 of them, duplicates.

                     

                    RESULT:  Same as top of this thread

                     

                    FIX:  Use "vi /etc/wpa_supplicant/wpa_supplicant.conf" to edit yours down to 1 un-corrupted entry. (Deleting the entire file is  not good. I tried it. Not sure about deleting ALL entries in file.)

                    Hope this helps. Sorry I just don't have time to provide more details at the moment.

                      Dave I love you! you are great! And the best solution.

                      It helped to me! For some reason I guess, OS thinks when you connected too many times to turn off wifi and don't look for it anymore!

                      You soultion helped me a lot!
