WIRELESS card SHOW unavailable

if it is on a laptop, try turning the wireless on and off several times by pressing f12 key. you haven't mentioned the pc config and os version. wireless have some issues in version 11.04 (un updated).

I have 11.04 but i use it from long time now and it was good

i use HP compaq

i try turrn off and on but no use

Can you give the output of:

sudo lshw -C network; uname -a; cat /etc/lsb-release; sudo rfkill list

Thanks
