cannot switch to ad-hoc mode!?

[HaPo]

Hello!
I can't switch my wifi card in ad-hoc mode.
I made
sudo iwconfig ath0 mode ad-hoc
reply was:
Error for wireless request "Set Mode" (8B06) :
SET failed on device ath0; Invalid argument

System spec:

product: Atheros Communications
phisical id: 0
bus info: pci@06:00.0
configuration: broadcast=yes
driver=ath_pci
driverversion= 0.9.4.5 (0.9.3)
multicast= yes


ifconfig returns

someone could tell me what are wifi and ath0:avah ??
Why There isn't eth1 like my other pc
I readed something about a virtual interface...and daemon avahi...but nothing of very useful!

The card functions perfectly in managed mode...
The pc is a notebook VGN-N21S

Please help!
Thank's in advance. H4p0

I guess this is because the correct way to set mode is

iwconfig ath0 mode Ad-Hoc (mode is case sensitive afaik)

I think you should read the following: http://en.wikipedia.org/wiki/Avahi_(software)

and maybe the following two if you wish:

http://avahi.org/wiki/AboutAvahi
http://www.zeroconf.org/

Avahi daemon is a lot more useful than you think, as it provides automagic configuration of (among other) network devices.

I receive the same error

[HaPo]

Connect My laptop (Atheros card) to my Desktop (BCM43XX)

YEAHH!!
I finally made it!
command

#wlanconfig ath0 destroy
#wlanconfig ath0 create wlandev wifi0 wlanmode Ad-Hoc

now I finally set up my card in Ad-Hoc mode but
doesn't seem to work...I receive some packet and I transmit but
the session doesn't comes up

iwconfig seems ok
device looks to be associated...
but I cannot ping between two pczz...

DOH!

any suggestions?

I post some info
