Edison Wifi does not connect

[Chris_M_1]

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
