ubuntu 16.04 oem config wireless

[ubuntushop]

Ubuntu 16.04 oem config prepare:
On first boot by the end user he has to fill in all data and select keyboard, language etc. Than oem config does configure and the user is logged in automatic or with password.
On that stage the wireless network stated "device not ready"
But after reboot the wireless network is ok.

Status changed to 'Confirmed' because the bug affects multiple users.

Reproduced on a derivative. Using 16.04.1 ISO remastered with the Sugar desktop. Used to work with 14.04.3. Log out and log in makes no change. Workaround is to reboot.

Can supply additional information if required. Let me know.

bug still present in 16.04.1

[James Cameron (quozl)]

Is caused by missing wpa_supplicant.

Alternate workaround is to start it manually;

    systemctl start wpa_supplicant

After this, wireless can be used. The reason reboot worked was that it did the same thing.

According to syslog, when the host name changes from oem-INVALID to user preference captured by oem-config, wpa_supplicant is stopped by systemd, but does not start again.

What systemd thinks of wpa_supplicant at the time of the problem:

# systemctl status wpa_supplicant
● wpa_supplicant.service - WPA supplicant
   Loaded: loaded (/lib/systemd/system/wpa_supplicant.service; disabled; vendor preset: enabled)
   Active: inactive (dead)

Hope that helps someone fix this!
