WiFi мост на 5Ghz. Проседание линка + link downs.
Добавлено: 24 окт 2019, 18:38
Настроен Wi-Fi мост (Channel 150 / 5750 Mhz/40 Mhz)/
С одной стороны №1 Ubiquiti (PowerBeam M5 400), с другой №2 Microtik (Sextant G-5HPnD, RouterOS 6.44.5).
Дальность ~2 км. Прямая видимость.
Линк встает. В статистике интерфейса:
Tx Rate до 216 Mbps
Rx Rate до 108 Mbps
Tx/Rx Signal Strength = -65/-70
Tx/Rx Signal Strength Ch0 -70 dBm
Tx/Rx Signal Strength Ch1 -78 dBm
Noise Floor -112 dBm
Signal To Noise 41 dB
Но! под нагрузкой Tx Rate/Rx Rate прыгают, опускаясь вплоть до 6 Mbps и даже вплоть до падения линка.
Конфиг см. ниже.
Что может быть причиной?
Спасибо.
P.S.
К №1 Ubiquiti подключено только два линка. Этот Microtik + в 200 метрах от Microtik стоит №3 Ubiquiti Nanobridge M5.
AirMax на Ubiquiti не используется.
В логах повторяется:
44:D9:E7:6A:14:AF@wlan1-gateway: lost connection, roaming
44:D9:E7:68:DD:39@wlan1-gateway: failed to connect, on 5750/20-Ce/an, association timeout
44:D9:E7:6A:14:AF@wlan1-gateway established connection on 5750000, SSID inet
44:D9:E7:6A:14:AF - это удаленная №1 Ubiquiti
44:D9:E7:68:DD:39 - стоящая в 200метрах №3 Ubiquiti
P.P.S.
Доступ к Ubiquiti отсутствует.
