hi all,
I'm playing with connman on my Ubuntu 17.04 laptop and got Ethernet going
ok, but only get "no carrier" error when trying to do a wifi scan. Could
someone please point me towards the right direction or give some hints on
how to debug this further.
Here's some details from my command line:
klasu@klasu-ThinkPad-T470p:~[0 0 0]$ connmand --version
1.33
klasu@klasu-ThinkPad-T470p:~[0]$ sudo connmanctl scan wifi
Error /net/connman/technology/wifi: No carrier
klasu@klasu-ThinkPad-T470p:~[0 0 0]$ sudo connmanctl technologies
/net/connman/technology/ethernet
Name = Wired
Type = ethernet
Powered = True
Connected = True
Tethering = False
/net/connman/technology/wifi
Name = WiFi
Type = wifi
Powered = True
Connected = False
Tethering = False
/net/connman/technology/bluetooth
Name = Bluetooth
Type = bluetooth
Powered = True
Connected = False
Tethering = False
klasu@klasu-ThinkPad-T470p:~[0]$ sudo rfkill list
1: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: no
Hard blocked: no
9: phy1: Wireless LAN
Soft blocked: no
Hard blocked: no
10: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
klasu@klasu-ThinkPad-T470p:~[0]$ sudo iw wlan0 scan |grep BSS|grep wlan0
BSS 4c:e6:76:22:aa:35(on wlan0)
BSS 68:7f:74:15:8f:aa(on wlan0)
cheers, klaus

Did you checked if wpa_supplicant is running ?
If not you can start it by hand
sudo wpa_supplicant -u
And try to see why it is not launched, perhaps an issue around dbus-launch.

wpa_supplicant seems to be running already and has the -u switch:
klasu@klasu-ThinkPad-T470p:~[0 127]$ ps aux|grep wpa_supp
root 1301 0.0 0.0 46552 6564 ? Ss joulu12 0:01
/sbin/wpa_supplicant -u -s -O /run/wpa_supplicant
Any further tips? :-)

I think a paste of your connman output can be useful,
can you run connmand -nd, and paste logs on pastebin.com ?
