Как устранить частые отключения WiFi от роутера MiFi?

Недавно я обновил USB-модем HUAWEI E153 до мобильного WiFi-маршрутизатора E583C .

Устройство предоставляет другим моим устройствам доступ в Интернет через Wi-Fi, пока я не окажусь в моем нынешнем офисе. От пяти до тридцати минут мои зависимые компьютеры потеряют соединение Wi-Fi.

Попытка восстановить соединение не удастся. Любые новые устройства, пытающиеся зарегистрировать свою сеть Wi-Fi, также не будут работать . Потребуется очень много времени, прежде чем он сможет «восстановиться», и адаптеры Wi-Fi смогут установить соединение и восстановить доступ в Интернет. Вместо этого я вынужден подключить USB-кабель для поддержания проводного сетевого подключения.

У моей коллеги есть аналогичная модель MIFI, HUAWEI E5830, с которой она сталкивается с точно такой же проблемой - хорошо на улице, гарантированное отключение в офисе.

Сначала предположим, что в здании слишком много других точек доступа Wi-Fi, поэтому я попытался переключиться между каналами передачи 1, 6, 11 и даже 13, но ни одна из них не дала лучших результатов. Расширяя журналы диагностики сети Windows, она показывает, что в районе насчитывается около 19 сетей, поэтому я предполагаю, что помехи настолько велики, что мое маленькое мифи-устройство не может конкурировать. Даже если я прикреплю расширенную антенну.

Ниже приведен диагностический журнал, в котором я не могу правильно определить, что я могу сделать, чтобы дополнительно устранить неполадки и, возможно, решить проблему в этой офисной зоне?
