The true problem concerns boot setup as already reported in:
rfkill turns all radios off after boot, regardless of setting before rebooting (Bug #163)

which provided the wifi Channel name, herein just called: wifi
$ sudo rfkill list
$ sudo rfkill unblock 0 (may be different number on your System)
$ sudo ifconfig wifi up
brough wireless function up
