I found a workaround.. seems that old method still works without change:
filling these informations to /etc/network/interfaces
iface eth1 inet static address ...... netmask ...... gateway ...... wireless-key ...... wireless-essid ..... auto eth1
and adding one line to /etc/resolv.conf
nameserver .....
with disabling networking in network-manager completely makes me connected all the time :)
