Подключение беспроводной сети на Ubuntu 15.10 (Intel AC 7260)

Я боролся с этим в течение некоторого времени, и понятия не имею, как это исправить. Я прочитал множество других сообщений на эту тему, но ни одно из решений мне не помогло.

Вот краткая версия моей проблемы: я могу сканировать сети, но не могу подключиться.

Мне удавалось подключиться раньше, но уровень сигнала был очень слабым. Как только я переместил машину дальше от маршрутизатора (<3 фута), я больше не могу подключиться вообще.

Вот вывод скрипта беспроводной сети:

########## wireless info START ##########

########## wireless info END ############

Я уже пробовал различные заклинания options в /etc/modprobe/iwlwifi.conf и, похоже, они не помогают. В настоящее время этот файл выглядит так:

# /etc/modprobe.d/iwlwifi.conf
# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system.  When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac80211

options iwlwifi 11n_disable=1

Любая помощь будет очень признательна!

Update Я обновился до 15.10, чтобы посмотреть, поможет ли более новое ядро. Карта по-прежнему ведет себя так же.

По предложению на ubuntuforums.org, я попробовал прошивку (17), так как она должна была повысить надежность этой карты. И снова никаких улучшений...
