wifi scan failing on ubuntu
by Klaus Anderson
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

/net/connman/technology/wifi

/net/connman/technology/bluetooth

klasu@klasu-ThinkPad-T470p:~[0]$ sudo rfkill list

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)
