Hi all,
 

I am experiencing a critical stability failure on my Deco network centered around the BE65 Pro (v1.1.3) firmware, which is causing constant client disconnection/reconnection cycling (session flapping) across all wireless bands.

It is crucial to note that my previous setup, utilizing three XE75 Pro units m, was rock solid and provided stable service for over a year. The instability began immediately upon introducing the BE65 Pro units and creating the mixed-mesh network.

I have performed exhaustive troubleshooting and isolated the issue to a fundamental bug in the BE65 Pro's client session management logic.

1. Hardware and Firmware Details

• Main Unit & Wired Satellite: 2x Deco BE65 Pro

• Firmware Version: 1.1.3

• Affected Clients: Numerous IoT devices (2.4 GHz) and high-bandwidth devices (5 GHz).

2. The Core Problem: Client Session Flapping

Devices on the network repeatedly disconnect and immediately reconnect every few seconds. In the Deco app, clients are constantly cycling between "Online" and "Offline," and in external apps (like Apple Home), devices remain stuck in an "Updating" state.

3. Exhaustive Troubleshooting & Conclusive Results

To conclusively isolate the issue, I performed the following steps, ruling out all common causes:

• Initial Setup Failure (Mixed-Mesh): The full 5-unit network (BE65 Pro Main + XE75 Pro Satellites) was immediately unstable, exhibiting severe steering failures and connection cycling.

• Test 1: Isolation to Pure BE65 Pro: I performed a full factory reset and configured the network using only the two BE65 Pro units (Main + Satellite). The network remained UNSTABLE, with the disconnection cycling observed across both 2.4 GHz and 5 GHz clients. This conclusively proves the bug is in the BE65 Pro v1.1.3 firmware.

• Test 2: Settings Elimination: I disabled all aggressive features, including Fast Roaming, Beamforming, and forced 20MHz channel width. The cycling persisted, ruling out a simple settings conflict.

• Test 3: Segregation Failure: I moved problematic clients to the built-in Deco IoT Network (dedicated 2.4 GHz, simpler logic). These clients also remained UNSTABLE, cycling constantly.

• Test 4: Preferred Deco Failure: The "Preferred Deco" function is non-functional for unstable clients (primarily on the IoT network), as they are failing to connect to the designated Deco unit.

The failure is confirmed to be a software bug that prevents the BE65 Pro from maintaining stable, persistent client sessions on any band, and it breaks core client management features like "Preferred Deco."

4. Action Requested

I have already opened a support case with TP-Link (Case Number: TKID251159167 ) but I haven't heard anything back yet.   
 

Is there any solution to my problems?

is there a access to a stable Beta or Official Firmware version that resolves the core client session instability. 

Is  the BE65 Pro firmware team is aware of this critical instability bug in version 1.1.3.?

I appreciate any help. Thank you!
