Thanks for reaching out. I understand that after switching to the Deco Mesh system, you are experiencing frequent disconnections where various devices (such as Ring doorbells, iPhones, and Watches) randomly drop off the network and appear as offline in the Deco app, even though some devices remain stable.

Here are some steps you can take to troubleshoot and resolve these unstable connection issues:

For client devices dropping or going offline (while Deco units show green lights):

1. Check Device Settings in the Deco App:
   • In the client list section of the Deco app, select each affected device and ensure that 'Speed Limit' is disabled.
   • Make sure the 'Mesh' option is enabled and 'Connection Preference' is set to 'auto' (these are the default and recommended settings).

2. Review Parental Controls:
   • In the 'Parental Control' section of the Deco app, verify that your devices are not accidentally restricted by any parental control profiles.

3. Optimize Device Connection:
   • Ensure your mobile devices are connecting to the nearest Deco unit with a strong signal. If possible, connect to the 5GHz or 6GHz band, as these provide better performance and reliability than 2.4GHz (which is not recommended for high-speed or latency-sensitive devices).
   • Try turning Wi-Fi off and back on for the affected device to force a fresh connection.

4. For 2.4GHz IoT Devices (like Ring doorbells):
   • If you have a Wi-Fi 7 Deco model (such as BE16000), go to the Deco app: MORE > Wi-Fi Settings > Advanced, and set the 2.4GHz Channel Width to 20MHz to reduce interference.
   • Also, under More > Advanced > Wireless Network Mode, select 'High Capacity' mode to improve 2.4GHz performance and capacity.
   • Use the 'Network Optimization' tool in the Deco app to automatically optimize your Wi-Fi channels.
   • If you have many Deco units and IoT devices, try temporarily powering off some Deco units to see if this improves stability for your devices.

Additional Tips:
• Make sure all Deco units are placed in open areas (not inside cabinets or corners) for optimal coverage.
• If you have a satellite Deco connected via Ethernet, double-check the cable and connection.
