Phenomenon Description

After updating the Deco M9 Plus Firmware to 1.8.1, some satellite units may no longer connect to the nearest Deco M9 Plus. For example, prior to firmware 1.8.1, a Deco X50-Outdoor would always automatically connect to the nearest Deco M9 Plus; however, after the firmware upgrade, the satellite Deco's signal is significantly weakened, and remains connected only to the main Deco — even with "Connection Preference" assigned to the nearest Deco M9 Plus.

Available Solution:

• Please refer to this link to submit the Deco App log: How to Submit Deco App Log

• Install the following Beta Firmware to verify whether the phenomenon is resolved.
