I use my wireless normally but when i put my laptop to suspend or hibernate (and sometimes after a normally restart) it seems unable (device not ready).. And i cant turn it. it back to normally after a restart. And the other problem, i didnt use wireless control (Fn+F9), i install samsung-tools and the others but i cant fix it. My computer samsung r522 and this problems same in ubuntu 11.10 and xubuntu 11.10.
Thank you for your answers from now..
