HAP ac lite cuts cable speed from 100Mbps to 20Mbps. How to eliminate?

Question

network hardware

Добрый день.
Скорость замерялась speedtest-ом, сначала кабель провайдера был воткнут на прямую в ноут
тест показал 94-97 Мбит/с на скачивание и 89-91 на отдачу, после поставили роутер, кабелем подключили к нему ноут.
Выбрали в speedtest тот же провайдера и несколько раз прогнали тест.
получили скорости: 18-24 Мбит/с на скачивание, 12-17 Мбит/с на отдачу.
Выкладываю конфиг роутера, может кто с таким сталкивался какие могут быть варианты диагностики?

Answer 1

Скорее всего из-за маскарадинга в нат, настраивайте srcnat

Answer 2

Во время замера через микрот проверить загрузку проца на нём, проверить не сыпятся ли ошибки на портах. /tool profile покажет, какая подсистема грузит проц.
