После обновления (свежая установка) до Trusty (Kubuntu - EDIT, а теперь и Ubuntu vanilla) я переключился на дальнейшую диагностику этого ). Я заметил проблемы с сетью.
Ровно каждые две минуты моя сеть на мгновение отключается, а затем вскоре возвращается в режим онлайн. Это ясно отражено в системном журнале:

Я не потратил слишком много времени на устранение неполадок, я только что установил день назад. Мне было интересно, если кто-нибудь видел эту проблему раньше? Я не помню, чтобы когда-нибудь видел это, когда был на Ubuntu 13.10 с тем же самым оборудованием только 3 дня назад.
Аппаратное обеспечение: Tecra R840-S8430 Сетевой контроллер: Intel Corporation Centrino Advanced-N 6230 [Rainbow Peak] (версия 34) Аромат: Kubuntu + Ubuntu Релиз: 14.04 LTS
Обновление - Больше информации (5/05/05)
Да, похоже, это разрывает мою связь. Вот некоторый системный журнал из типичного дропа, я должен отключить / повторно включить Wi-Fi, чтобы восстановить его:

Это так расстраивает. Я не всегда могу быть на cat5. Как я уже говорил, 13.10 этого никогда не произойдет. Я действительно не хочу понижать рейтинг. Есть ли способ использовать драйверы Wi-Fi с 13.10?
Кроме того, я изменил свою защиту Wi-Fi с WPA2 на 128 WEP и до сих пор отключался только раз в несколько часов. На WPA2 это было в среднем каждые 10.
