</span>Hi,<br>
<br>
<br>
The TYPE of cdc-wdm1 interface is "gsm".<br>
<br>
On the other hand, NetworkManager.conf has:<br>
<br>
CONFIG: [keyfile]<br>
CONFIG:   unmanaged-devices=*,except:<wbr>type:wifi,except:type:wwan<br>
<br>
<br>
note, that "except:type:wwan" does not match "type:gsm".<br>
<br>
<br>
<br>
<br>
<br>
Probably this configuration comes from something like<br>
  /usr/lib/NetworkManager/conf.<wbr>d/10-globally-managed-devices.<wbr>conf<br>
If you create an empty file<br>
  /etc/NetworkManager/conf.d/10-<wbr>globally-managed-devices.conf<br>
the one<br>
from /usr/lib will be shadowed.<br>
<br>
Or, put another file<br>
  /etc/NetworkManager/conf.d/99-<wbr>my-managed-devices.conf<br>
with<br>
  [keyfile]<br>
<br>
unmanaged-devices+=except:<wbr>interface-name:cdc-wdm1<br>
or just reset it<br>
entirely:<br>
  [keyfile]<br>
  unmanaged-devices=<br>
<br>
<br>
<br>
<br>
best,<br>
