esu visiškai tupas... :(
Kokie failai atsakingi už lano nustatymus?
Man nė iš šio nė iš to atsisakė wlan0 konfigas (po python upgreido).
Ką pažįstu papostinsiu:

čia matau, kad wlan0 trūksta IP

dar kartą rankiniu būdu pereinu:
	mybox ~ # ifconfig wlan0 192.168.1.55
	mybox ~ # iwconfig wlan0 mode Managed
	mybox ~ # iwconfig wlan0 essid ot key s:*****
	mybox ~ # dhcpcd wlan0


tada suveikia. O kas tokio sukonfigūruota negerai, kad automatiškai  
neužsimeta IP? Ir resolv.conf
nameserver dingsta po kompo perleidimo.
