Уважаемые господа, поиском решить проблему не смог так что пишу сюда (первый раз сильно не пинайте)
Проблема следующая: есть небольшой роутер на FreeBSD 4.7. Внешний интерфейс rl0 подключен к радио точке доступа провайдера Mikrotik. До этого стоял радио-бридж Cisco BR350 после замены его на микротик начались проблемы с линком. Пинг от роутера (FreeBSD) до шлюза (Mikrotik) постоянно прыгает от 1.5 мс до 2000 мс с постоянными потерями. Провайдер говорит что проблемы у меня. Физически устройства стоят в одном помещении, кабель заменил, сетевую карту менял.
Вот логи с фряхи, ip микротика 89.18.128.161 :

Буду очень признателен если кто-нибудь толком расскажет как продиагностировать эту проблему ну и конечно решить.
