Обрывы связи на частоте 5ГГц

Клиент подключен к точке доступа на частоте 5ГГц (ноутбук Sony Vaio) (SSID: WiFi-UE-Group). Точки доступа находятся в едином WDS. Конфигурация стандартная (cisco AP1142N-R-K9). При передачи данных начинаются обрывы связи и переподключение. Сигнал в районе -60 -65dbi, при этом на интерфейсе видно следующее:
