Падает сеть

Вот такая вот проблема , у меня роутер wifi конекчусь к нему через wicd, после
перехода на ядро .......29-r5 , прихожу к компу а связи нет, даже индикатор wifi
не горит, пробую перезапустить wicd --начинает конектится и затем пишет
неправильный пароль, хотя индикатор не загорается и я так понимаю карта не
поднимается, поднимаю насильно ---загорается индикатор, запускаю wicd ,
индикатор гаснет и опять неверный пароль, помогает только перезагрузка ОС, при
оной все поднимается автоматом и работает. Что происходит

вот маленький кусочек из dmesg
