Ubuntu 12.04: WiFi, не работающий после приостановки

вот моя конфигурация: - S.O.: Ubuntu 12.04 - Ядро: 3.5.0-25 - Ноутбук: Sony Vaio VGN-FZ21E - автомобиль WiFi: Intel PRO/Wireless 3945ABG [Golan] - драйвер: iwl3945

После приостановки мой WiFi не работает, даже перезапуская сеть или перезагружая модули. Кажется просто, что карта выключена, и Ubuntu не может общаться с ним. Я думал это, когда я взглянул в/var/log/syslog, и я нашел это:

После обновления ядра к 3.5.0-25, я заметил новый модуль, названный iwlwifi, который также присутствует в системном журнале, и у него, кажется, есть диалоговое окно с беспроводной картой:

Mar 12 09:48:16 pablo-laptop kernel: [  209.569037] iwlwifi: Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree:

Какая-либо идея?!

12.03.2013

Вот вывод lspci-nn | grep 0280:

06:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection [8086:4222] (rev 02)

Управляйте, чтобы ls/etc/modprobe.d | grep iwl дал что-либо....

13.03.2013

iwlwifi не присутствовал в/etc/modules и был успешно добавлен к/etc/modprobe.d/blacklist.conf.

Я пытался приостановить и возобновиться в течение трех раз, но в 4-й раз проблема произошла.

p.s. Та же проблема произошла с Ядром 3.2, где iwlwifi не присутствовал.

ВАЖНЫЙ: менеджер по Обновлению советует мне устанавливать 'платформу управления сетью (общие файлы для Wi-Fi и мобильный)' и 'платформу управления сетью (диалоговые окна GNOME для Wi-Fi и мобильный)'. Я должен установить их? Что они делают exaclty? Может влиять на мою проблему?

14.03.2013

Добавленный следующая строка в файле/etc/pm/config.d/config

SUSPEND_MODULES="iwl3945"

После некоторых успешных тестов проблема произошла с новыми ошибочными сообщениями в Системном журнале:

iwl3945 0000:06:00.0: bad EEPROM signature,EEPROM_GP=0x00000007

Затем я сделал другой тест, который был успешен, и это сообщения в системном журнале:
