I can't connect through the wireless interface

[Amimusa MAN U]

Hello all,

The Wireless network was working fine, but after unable it and enable
later it is not working.

Here is the /etc/network/inerfaces file:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.2.110
netmask 255.255.255.0
gateway 192.168.2.1

auto eth1
iface eth1 inet static
wireless-essid manou
address 192.168.2.120
netmask 255.255.255.0
gateway 192.168.2.1

auto eth2
iface eth2 inet dhcp

auto ath0
iface ath0 inet dhcp

auto wlan0
iface wlan0 inet dhcp


and here is output when I try to start the network daemon:

root at nomada:/etc# /etc/init.d/networking restart

I also have tried with dynamic configuration.

The wireless interface and connection works fine with other OS.

What can I try/check? Please, any help ? 

Thanks in advance.
