same error

- what can I view about:

wlan0    Interface doesn't support scanning : Device or resource busy

p.s.
I virtualized:

kubuntu16.04 works OK
kubuntu18.04 dont works
ubuntu14.04 works OK

As the dongle behaves in your Debian and mis-behaves in your Devuan, there must be some difference in the code involved, obviously. The start point for tracking that down would be in the versions: of the kernels, of the ath modules and firmwares, of the hotplug handlers, etc. Perhaps you can make a table. Then it would be possible to experiment by aligning versions where possible, and by inspecting the differences more exactly otherwise.

btw, there is also the iw tool (from wireless-tools) for

# iw dev wlan0 scan

Rumours has it that sometimes that works where iwlist fails.

- rfkill are not blocked

- auto or allow-hotplug same problem

- is OK that I view nothing running:

dmesg|grep wlan

Have you tried with rfkill (tool for enabling and disabling wireless devices)? As in a "googled" example:

# modprobe -rf ath9k ath9k_htc
# rfkill unblock all
# modprobe ath9k ath9k_htc

I'm not sure what's the difference from Debian though. It would depend on versions, since the code for bringing up interfaces has had some development recently (last few years). Not long ago, it had a bug where the script could query the interface state too early after power-on. The patch against that problem was to add a sleep into the script between starting the interface and checking its state.

You could also try to use the "auto" method rather than "allow-hotplug", to let the networking init script raise the interface instead of (e)udev.

ok try to change the proto= WPA line to proto=RSN

and ifdown eth0 to see if there is a conflict between eth0 and wlan0

but you shoud try wicd more secure and has a gui .

Re: wireless problem on qemu

dummy@example.com (sacarde) — Mon, 23 Apr 2018 15:38:35 +0000

this is my /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
network={
ssid="NETGEAR"
proto=WPA
key_mgmt=NONE
pairwise=TKIP
group=TKIP
}

but after reboot, same problem:

eth0 have an IP
wlan0 no

Re: wireless problem on qemu

dummy@example.com (wdq) — Mon, 23 Apr 2018 15:24:09 +0000

Well then just modify like this the content of wpa_supplicant.conf

 key_mgmt=NONE

and do not add the

  psk="password"

line .

Re: wireless problem on qemu

dummy@example.com (sacarde) — Mon, 23 Apr 2018 15:19:17 +0000

my network has only essid NETGEAR

no any other key/password

what I have to set this:

ssid="network_id"
psk="password"
proto=WPA
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP

Re: wireless problem on qemu

dummy@example.com (wdq) — Mon, 23 Apr 2018 15:16:48 +0000

Well let`s try this
apt-get install wpasupplicant

 apt-get install wpasupplicant

now you need to create a configuration file so

nano /etc/wpa_supplicant/wpa_supplicant.conf

Add the next content in your config file where you have to change network_id and password with your own

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1

network={
  ssid="network_id"
  psk="password"
  proto=WPA
  key_mgmt=WPA-PSK
  pairwise=TKIP
  group=TKIP

Now let`s modify the network/interfaces

nano /etc/network/interfaces

and add modify like this

auto wlan0
  iface wlan0 inet dhcp
  wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

and give a reboot

Hope this helps !

in both systems I dont have wpasupplicant

Re: wireless problem on qemu

dummy@example.com (wdq) — Mon, 23 Apr 2018 13:34:37 +0000

have you installed wpasupplicant , if yes just add it in your etc/network/interfaces

 auto wlan0
  iface wlan0 inet dhcp
  wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

restart networking

hi,
I use same usb-wireless (Atheros AR9271) in 2 virtualized system:

1) debian/sid
2) devuan

I use same configuration:

allow-hotplug wlan0
iface wlan0 inet dhcp
wireless-essid NETGEAR

in debian system, wlan0 get IP address OK
in devuan system I receive error:

in both system eth0 in dhcp works OK

what can I check?
