Network crash in pseudo ad-hoc

[eleftherios.skoutaris at uni.lu]

Sorry but I also forgot to add my iwconfig which is weird after the
setting to pseudo ad-hoc:

[root at monaco ~]# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

As you can see the signal level = noise level. The card after this is
blind!!! Dead link.i cannot ping anything...
