Передо мной Acer V5 171, на котором установлена чистая установка Windows 7 X64 с пакетом обновления 1 (SP1) будет иметь все текущие исправления и обновления, с последними драйверами от Acer версия bcmwl664.sys - 5.100.196.18
Если я подключаюсь к BT "Home Hub 2" (Speedtouch с прошивкой BT), беспроводная связь работает отлично
Если я подключаюсь к Cisco 877w под управлением c870-advipservicesk9-mz.151-4.M4 с конфигурацией в соответствии с ниже, после того, как он передал небольшое количество данных, он синего экрана

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (7e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Arguments:
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff88005a4a6c9, The address that the exception occurred at
Arg3: fffff88009eb4508, Exception Record Address
Arg4: fffff88009eb3d60, Context Record Address

---------
Поскольку драйвер "отлично" работает с "домашним концентратором" BT, я на 99,99% уверен, что это не проблема с повреждением файла, однако я уже скачал драйвер снова, попытался удалить WiFi NIC, удалив файл .sys. и переустановка с нуля безрезультатно.
На веб-сайте Acer доступен "более поздний" драйвер Wireless LAN_Broadcom_6.30.59.78_W8x64UW8x86U_A, но, похоже, он предназначен для другого набора микросхем, поскольку Windows не позволяет обновлять драйвер до его содержимого.
Я вижу небольшое количество повторов на беспроводном интерфейсе на Cisco. Регистрация на устройстве BT, однако, жалкая.
