Debian 8.2 - AP на Intel Centrino Advanced-N6205 (62205ANHMW)

Всем добрый!

Собрал роутер на Debian 8.2 По проводам все прекрасно работает, но с wifi какие-то непонятные грабли - периодически отваливается. Точнее даже не отваливается напрочь, а резко падает скорость до состояния что ничего не грузится. Через какое-то время само отвисает. И сама скорость тоже так себе (Примерно в 2 раза медленнее древнего роутера Dlink DIR-628). wifi отваливается на стороне роутера - 2 телефона, планшет и комп одновременно отваливаются.

1. Обновить firmware карточки на самый последний (https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-6000g2a-ucod...)

2. Обновить ядро - поставить из бэкпортов версию 4.5

3. Убирать недефолтные настройки из hostapd.conf по одной, играться с флагами ht_capab

4. Читать логи ядра и hostapd

5. Если всё это не поможет то выкинуть её и купить нормальный Atheros - они пашут без проблем.

а что за железка отвечает за вайфай?

Ответ на: комментарий от blind_oracle

Вот это помогло: /etc/modprobe.d/iwlwifi.conf 

options iwlwifi power_save=0 auto_agg=0 swcrypto=1 11n_disable=8
Теперь скорость стала как на роутере. Отваливается сейчас или не отваливается еще не знаю, отпишусь позже.
