Беспроводное соединение внезапно отбрасывает Intel 3945ABG

У меня есть старый ноутбук СПУТНИК Toshiba L350-150 с сетевой платой Intel® PRO/Wireless 3945ABG.

Я использовал mkusb для создания персистентной карты с интерфейсом USB с Lubuntu 17.10.

Начальная загрузка ОС хорошо работает, и беспроводное соединение работает хорошо, пока внезапно это не отбрасывает. Администратор сети указывает 'На устройство, не готовое'.

Последнее встроенное микропрограммное обеспечение 15.32.2.9 используется (см. вывод lshw).

Какие-либо идеи, как зафиксировать это?

Поиск и устранение неисправностей

Не решил проблему

sudo service network-manager restart

sudo modprobe -r iwl3945 && sudo modprobe iwl3945

Вот некоторый вывод:
