I see the posts about naming interfaces. So, if i want use the systemd recomendation naming how should instead configure netcfg? The wiki is not up to date says wlan0 and eth0...
The wiki is up-to-date, you just need to read it:
Set INTERFACE to the correct wireless or Ethernet interface. This can be checked with ip link and iwconfig.
Please make some effort yourself before opening threads here: don't be a help vampire.
