Now I have disabled CONFIG_WIRELESS_OLD_REGULATORY and I have installed CRDA and iw. After setting the country I'm able to create the ad-hoc IBSS between the two PCs. According to my opinion the error message posted in the original message of this thread might be misleading for the user: the network card doesn't enter in ad-hoc mode because the country for the CRDA is not set while the error says that the ad-hoc mode is not supported. What do you think about?
