Провайдер Инфолайн. К роутеру подключены 2 компьютера. Очень часто обрывается связь на пару минут. При этом в закладке ТЕСТ отмечены как FAIL либо все пункты "Test the connection to your Internet service provider" либо некоторые. В чём проблема, подскажите

Включайте лог устройства и приводите здесь информацию со страницы Status > Log.

я так понимаю, что нужен лог на оранжевом фоне
вот только что оборвалась связь и вот лог

Судя по логу, соединение успешно устанавливается.
Опишите, какие именно тесты устройства заканчиваются неудачей и с каким интервалом.
