Critical Instability/Session Flapping on Deco BE65 Pro (v1.1.3) - Affects All Bands/Clients
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!

For anyone who is still having issues in this forum thread.
Please refer to this link to submit the Deco APP log. If you submitted the log alread please do it again. I'm sick and tired of these firmware issues and tp-link needs to fix them.

@David_TP-Link David, do you have any updates with resolving the critical firmware issues effecting this Model, BE65, and potentially other models that use this firmware?

This has actually gotten worse somehow tonight, and I haven't changed anything. My 5 GHz network in particular keeps dying under barely any load. Like 10-20 Mbps according to the Deco app. On my laptop, PHY/link speed will start dropping after a bit and then dips below 100 to nearly 0 and I start getting frequent disconnects until I reconnect to the Wi-Fi and link speed goes back to around 2100-2402 for a bit, but remains unstable and jumps around a lot.

Support had me disable 2 of my iot switches for testing as they were cuasing heavy traffic. Did that and no improvements.
Also today I woke up to an ISP outage, and for some reason that caused half of my devices to go offline, even a wired device. What's going on with these routers?

@Murtaza911 I completely understand your frustration.
My network is a single SSID, no switches, nothing fancy. I'm still unable to use my soundbar via my Bose app, in addition to various clients dropping off the Deco, will connect to another one, yet not work, even though you can see it connected in the Deco app. I'm back to having throughput issues using Microsoft Teams, initally the call will be fine, then the video becomes really choppy.
I find it hard to understand why TP Link is not able to locate the issue within their own firmware. Especially wth a Senior Engineer reaching out to you.
We could keep this threat, and many others like this one alive until these issue are resolved.

@David-TP Are you able to provide this tread an update on what TP Link are doing to resolve the firmware issues myself and others have raised?
I have provided router logs, most recently this morning as my deco's are now randomly crashing, returning back to a start up yellow light, and after a few minutes returning back to a green light. This is in addition to all the other critial firmware bugs version 1.2.0 has introduced.

Ever since my remote session with the TP-Link support engineer, my network has been a lot more stable. I'm only getting a few devices going off line now.
They told me by email we can do another session to sort these out as well. So just making a list now to see if there are any consistent ones going off line or if its random.
One weird thing I am noticing with my Apple Home Pods, is when they go off line, they come back online with a different mac address and it shows up as a wired connection. I think this has to do with Apples privacy features but not 100% sure.
Only other problem I experienced was when my ISP went down, all Ethernet ports on the main node stopped working. Google says this is becayse of the auto wan detection, so maybe they can disable this feature as well when we have our next remote session.
I have also added backmy remaining extra XE75 Pro. The first time I added this extra one the entire network went crazy and everything started disconnecting. But now everything seems ok!
I think I'm feeling confident enough to keep these BE65 Pros, and not return them.

@Murtaza911 I'm happy to hear you've had some progress.
However you cannot have an engineer remote into your router when there is an issue, and hopefully they've found what are causing these problems and reissue an update for everyone.
I have some wifi only clients that show up as wired in the deco app, including my iPhone 17 pro today, some led blubs and my robot vacuum cleaner. So figure.
Biggest gripe for me right now, my soundbar not being and to be control via its app, therefore I lose some functionality, and, the deco randomly crashing; on top of what I have previously mentioned.
I hope, and I'm still awaiting an update from TP Link. Let's see if they do the right thing by people who have bought these.

@Murtaza911 can you let us know what changes were made so maybe it'll help the rest of us out? Thanks!

I agree, I don't think it's reasonable to require an engineer to come in and fix each customer's problem. Hopefully they can take their findings and apply to to a firmware update soon.
Im having the same issue where sometimes a device disconnects and it shows up as wired the next time it connects.
It's a shame, because on paper these are excellent pieces of equipment. Especially for the price, when comparing to something like eero which is a lot more expensive and has a subscription for things included on these routers for free. Unfortunately these don't work lol.
I personally haven't made any changes. The tpnlink engineer remoted in and fixed everything. So I have no idea what they did. They ran a bunch of commands through the terminal and sshd in.
