Прошел почти месяц, и интернет меня подвел, я не могу найти решение этой проблемы.
Мой WiFi периодически отключается на 30 секунд - 30 минут. Он часто впадает в состояние постоянного отключения, если я пытаюсь подключиться к нему снова.
Проблема сохраняется в WPA2-Enterprise (аутентификация: PEAP, внутренняя аутентификация: MSCHAPv2), стандартном WPA/WPA2 и открытом Интернете.

Также, даже когда интернет работает, я обычно теряю ~15% пакетов, тогда как на моем разделе Windows я теряю <1% после 30 минут пингования. Я не уверен, связано ли это или нет.
