Thread: WIFI usb TP-LINK TL-WN821N

  1. #1

    Default WIFI usb TP-LINK TL-WN821N

    Проблема началась еще в opensuse 11.4, сейчас обновился до 12.1, но проблема осталась. Заключается в том, что
    через некоторое время отваливается usb адаптер wifi TP-LINK TL-WN821N. Грешил на сюспенд сделал следующее echo -1 > /sys/module/usbcore/parameters/autosuspend. Потом думал на павер менеджмен и в /usr/lib/pm-utils сделал чтобы не уходил в энергосбережение. Потом подумал что то с прерываниями и в грабе передал параметр pci=nomsi , но результатов никаких свисток отваливает, особенно на торентах заметно.
    Логи привожу ниже, после которых свисток умирает. Может у кого есть мысли?

    Особо не вникал, но смущает строчка:
    kernel: [ 8160.610272] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

    да меня тоже, но такой лог не всегда например сейчас при отвале вообще в логах пусто и появляются записи уже только после вытаскивания устройства.

    Я авахи демон вообще вырубил, мне он как бы не нужен. С другой стороны можно его врубить, я уже поправил конфиг чтобы сначала в днс смотрелись записи,а потом в mdns, а то тормоза были с днсом.

    Был такой прикол, открываешь браузер вводишь например mail.ru и через секунд 10 только страница вся целиком грузится. Погуглил нашел что avahi влияет, а точнее в файле /etc/nsswitch.conf стоит сначала искать запись через mdns, а уже потом в dns. Как только днс впереди поставил страницы махом открыватся стали. Ну и чет решил отрубить avahi и стали лететь dbus-daemon[1147]: dbus[1147]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.Avahi.service': Unit dbus-org.freedesktop.Avahi.service failed to load: No such file or directory. See system logs and 'systemctl status dbus-org.freedesktop.Avahi.service' for details. Как они связаны с усб вайфаем, с его отвалом?

    Обновил вчера ядро до 3.1.4 сейчас сижу на работе, залез NX клиентом на домашний комп на котором данный усб вайфай, час работы и снова отвалился свисток. Не могу понять уже куда рыть. Фирмваре последние стоят, в сон уводить отключено, энерго сбрежение тоже.

    Забыл сказать под windows работает без проблем. Да еще,до этого был усб вайфай dlink dwa-110 вроде, работал последнее время тоже также отваливаясь периодически, текущий девайс купил только ради замены для избавления от глюков и увеличения скорости, т.к. длинк g стандарта, а этот n тсандарта. Мать кстати на nforce 750a(GF8200) может чипсет плохо работает в линухе.
