Здравствуйте. Посоветуйте, пожалуста, что-нибудь по следующему вопросу:

Есть ноутбук со встроенной wireless карточкой Intel Corporation Centrino Advanced-N + WiMAX 6250 (rev 5f). На нём - Ubuntu 11.04. Проблема в том, что иногда не могу подключиться к wi-fi сети. Пытаюсь часами - безрезультатно. А потом вдруг всё спокойно подключается. Не могу понять в чём дело.

Вот, что записалось в syslog:

Может быть, ему просто времени не хватает, чтобы подключиться?

С паролем все в порядке. Здесь же на форуме прочитал совет вытаскивать шнур питания из розетки при отключении компьютера. Виндоус тоже посоветовал выключить питание, подождать 10 секунд и включить обратно) Неужто это единственное, что можно сделать? То есть, проблема в железе?

Ноутбук Asus U43F. Может кто-то еще с этим сталкивался?
