» Высокий пинг на Wi-Fi

Ребят выручайте, сломал уже всю голову.

Суть проблемы:
Есть локальная сеть, на ней 60 машин. Поставили отдельно Wi-Fi и дали доступ.
В итоге, работа Wi-Fi очень странная, то порой пинги 1-10 мс, то 2500-4500 мс или вообще не отвечает. И причём по времени каждый раз по разному.

На что грешили:
1) Роутер был в связке с МФУ, отсоединил МФУ пинги стали нормальные, но ненадолго.
2) Думали, что роутер загибается (ASUS RT-N66U), купили Zyxel Keenetic GIGA II, но ничего не поменялось.
3) Обратились в поддержку Zyxel они посоветовали программы:
InSSIDer - WirelessNetView - Free Wi-Fi Scanner
Мол просканируйте сеть и выберите нужный канал. Сделали, ничего не поменялось, только как и в прошлый раз, на время помогло.

4) Думали тухнет прошивка, поставили на ASUS Merlin Build, снова тоже самое.

5) Думали торренты, но это никак не отследить.
6) Возможно кто-то с телефона что-то качает, но пробовали сменить пароль и посидеть на этой точке с 1 аккаунта, с пингами никаких изменений не произошло, тоже прыгали.

В общем жду советов и примеров решений, что можно протестить, щас пока стоит ASUS RT-N66U (Версия прошивки: 3.0.0.4.376.45_0 (Merlin Build)). Готов дать дополнительную инфу если требуется.

Цитата:
поставь ширину канала 20 Мгц

снизь мощность до 80% или 60%
канал руками на 1Й

Щас поставил следующее, посмотрим что получится:

Может есть какой-то вариант вычислить кто забивает канал?

Потому что ради эксперимента, я взял ещё одну точку и на неё повесил только 2х пользователей, и она работает исправно.
