@warmy Если использование роутера С64 еще актуально, напишите, пожалуйста,  по данной проблеме на support.ru@tp-link.com.

  @warmy купил позавчера C64, и с Билайном та же проблема. Пробовал разные прошивки, не помогает. Свзь периодичесть пропадает (((

  @dmitry10 Я не смог справиться. Поставил Asus за 300р, работает очень стабильно теперь. От тплинка избавился.

  @User13542 Вы столкнулись с похожей проблемой? Могли бы вы приложить системный журнал из меню настроек роутера? https://www.tp-link.com/ru/support/faq/3055/

Добрый день!

У меня аналогичная проблема. 

Обращался в ТП, обращался в сервисный центр, по итогу впустую потраченное время. Все знают о проблеме и скидывают ответственность на Китай, мол ждите от них новую прошивку. Когда она будет неизвестно.

Уже 2 месяца роутер лежит кирпичем, ужасно огорчён таким сервисом. 

  @Vasilisa1 

Написал ещё раз в сервис, ТП и на фидбэк. Уже неделю нет никакого ответа.
