На новом ноутбуке Dell Vostro V131 вылезла проблема с wifi.
После загрузки некоторое время связь работает стабильно, потом через 10 минут, через час, как когда начинает сильно тупить. Пробовал подключаться к разным AP (в n и g) - без разницы.
Система Simly Linux.

У товарища точно такой же ноут, но под Gentoo, ядро 3.2. Проблем нету.
Есть возможность прикрутить ядро посвеже без сборки ручками самому?
