hwinfo output from Leap 42.2 installed

I ran the NET installer on a Lenovo B51-80 with ethernet card and wlan
wifi/bluetooth card. I attach the output of hwinfo.

The NET installer snapshot 2017-01-17 launches a DHCP request to the ethernet
card, which is not connected and fails to pick up the wlan card: the
installation stops because of missing installation media. The same behaviour on
the previous snapshot (2017-01-12 if I'm not mistaken).

Apparently the wifi related kernel module is loaded (iwlwifi).

Last time I ran a Tumbleweed NET installer (September 2016 IIRC), it picked up
correctly the wifi connection.

Work around: Tumbleweed DVD installer or Leap installer + online upgrade.
