Unable to setup network in ad-hoc mode, Ubuntu

Question

WiFi

Good evening!

Actually there is an ubuntu 10.04 machine, on it a wi-fi card VIA VT6655
It is necessary to configure the network in ad-hoc mode.
the interface is put into ad-hoc mode, but the essid cannot be set. and after transferring the eth1 interface to the active state, the other wi-fi machine does not detect the network. how to be? Tried combinations and no luck.

# iwconfig eth1 essid "My Network"
# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

eth1 802.11-a/b/g ESSID:""

vntwpa no wireless extensions.

# ifconfig eth1 up
# iwconfig eth1 essid any# iwconfig eth1 essid on

Answer 1

ifconfig wlan0 down
iwconfig wlan0 mode ad-hoc
iwconfig wlan0 channel 1
iwconfig wlan0 Bit 54Mb/s
iwconfig wlan0 essid 'My Wifi'
iwconfig wlan0 key "s:ca188"
ifconfig wlan0 192.168.2.1 netmask 255.255.255.0 up
iwconfig wlan0
ifconfig wlan0 up
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

Raises a point with the name My Wifi and the key ca188.
So that doesn't work either?
