Здравствуйте.
У нас имеется две сети, состоящих из точки доступа DWL 3200 AP , компьютера и трех терминалов сбора данных casio dt-x7. Сети находятся в разных зданиях.Версия прошивки точек 2.50 . Терминалы работают под управлением ОС Windows CE 5.0. Точки подключены к источнику бесперебойного питания.
Примерно раз в день вайфай соединение с терминалами рвется и восстановливается только после перезагрузки точки через веб-интерфейс или после выключения/включения питания точки . При этом через Ethernet точка доступна. Такие сбои происходят в обоих сетях.

Настройки вайфай соединения:

Wireless Band :IEEE802.11g
Mode: Access Point

SSID Broadcast Enable
Channel 1 2.412 GHz Auto Channel Scan off

Authentication WPA-Personal
PassPhrase Settings
Cipher Type TKIP
Group Key Update Interval 1800 Sec
