2.4 GHz network VERY unstable with Deco XE70s
I am experiencing an issue with the 2,4 GHz networks provided by my XE70 Pro mesh (3 nodes). The mesh provides 3 networks: main, IoT, and Guest. The IoT and Guest are 2.4 GHz only. The problem became apparent when my Wyze cameras were often VERY slow to connect to and sometimes even appear offline. These camera are 2.4 GHz only and are on the IoT network. Thought it may be a coverage issue so moved some cameras closer as a test, but no luck.
After lots of Googling research and seeing other reports of similar issues, I started to look for tools to help me diagnose my particular issue. I found a tool called WIFI Explorer which has provided some interesting insight into the behavior of my network. I'll use screenshots below to tell the story. Since I have 3 XE70s in my mesh network, there are 3 versions of each of my networks (main, IoT, and Guest) visible at any given time.
I'll start by showing a picture of the signal strength of my 5 GHz network from the XE70 node that I am closet to:

The signal strength remains nice and flat for the 5 minute duration shown, which is what you would expect of your network. This is consistent across all XE70 nodes regarding the 5GHz network. Never appears to be a drop in signal strength.
However, I'll now show the signal strength for all 3 nodes for the 2.4 GHz IoT network.
Node 1 - closest to my location:

Node 2 - Room 2

Node 3 - Room 3

All 3 nodes show VERY frequent times of complete outage during the same timeframe! This also happens on the 2.4 GHz network of my main network and Guest networks so is common to the system. I thought perhaps that it may be something in TP-Links implementation of a mesh network, but there have been times when ALL THREE are out at the same time giving me ZERO 2.4 GHz network coverage and wreaking havoc on my 2.4 GHz-based devices - particularly my Wyze cameras to the point where they are damn near useless.
I certainly HOPE someone can help here as I really want to like TP-Link products as I have quite a few. And I will be MORE THAN HAPPY to admit ignorance if it is something that I am doing wrong. Nothing special about my configuration as it is as it was out of the box. No fancy config here.
I am quite remote with the next neighbor about 1/2 mile away, so I would not think interference plays a part here.

Hi @David-TP I am on 1.3.0. I still have unstable connection with some iOT devices using 2,4Ghz network

Hi, an I right in thinking that the latest officially released firmware for the XE70 Pro is still 1.2.11? That's what mine have installed and the app says no update available. It's also the latest version I can see on the TP Link download website.
I see people have installed beta versions sent directly from the support team, and some suggest they've had a more up-to-date release pushed through the app (although it's unclear if that's for the XE70 or the XE75).
I'm suffering the the same WiFi dropouts as everyone else and am wondering if I should try to get hold of a beta release, just wait for an official update, or if for some reason I'm not getting new firmware pushed to me.
Thanks for any insight you can give.

I took the plunge and upgraded to the 1.2.14 beta 20250217 posted by @David-TP , on the basis I could downgrade again if necessary.
I just wanted to flag that installing that firmware immediately blew up my managed network switch. I only have one for legacy reasons and am about to move to an unmanaged switch but it might be helpful for people to know:
My switch had STP turned on for some ports as I also have a Sonos system with multiple wired devices and if you use a managed switch, STP is required.
STP was turned off for all the ports which had a mesh secondary node attached because if STP is turned on, wired backhaul doesn't work.
On the main deco, STP was turned on because it shared that port (via an unmanaged switch) with a Sonos device. But that's OK for the main Deco.
That setup worked fine for both Sonos and Deco on firmware 1.2.11. But after moving to 1.2.14, my managed switch detected a network loop and shut down the ethernet link between the main deco and the switch (and hence the router). I guess this beta firmware is more aggressively connecting between nodes on WiFi as well as ethernet backhaul and that is triggering a loop which wasn't previously there.
I recognise that managed switches and STP are complex technologies for home use and I'll report back again on the effectiveness of the new firmware once I've taken delivery of the unmanaged switch. But I wanted to post this as others may also be experiencing problems if they have a managed switch in their system, and these things are hard to diagnose so knowing about the issue might be helpful.

@David-TP bought these yesterday.. and now I have big problems with 2.4ghz.. XE75 using firmware 1.4.5 it keeps kicking me out from the network. So all my bulbs cameras etc is going offline. Beam and roaming is off. I created a IoT network for just this purpose.. but is keeps giving me alot of problem.

@rednake I'm still on the beta firmware 1.2.14, so I can't comment on the issues with the version you're on, other than to say that some people on this thread have said that new versions of the firmware sometimes add back problems that were fixed in previous versions!
Prior to moving to the beta firmware I'd turned off beam forming and fast roaming, as these are known to cause problems. Moving to beta 1.2.14 helped quite a bit but I got a further dramatic improvement when I turned beamforming and fast roaming back on. I know - that's crazy. But it improved things for me and it's easy to test, so I'd give it a try.

@RB777 The latest firmware on website is 1.2.11 which was released in 2024.

@ARGamingPK1 There have been beta updates since then. The one I use is here:

but there have been further updates since.

@RB777 This beta is the latest from 2025 and what was your issue? Are you facing 2.4 GHz problems? 20 MHz and 40 MHz issue?

Hi, thank you very much for the feedback.
I've left a message with the beta firmware for Deco XE75_v1 that has improved the 2.4GHz stability. Could you please help me test whether it helps or not?
Wait for your reply.
Best regards.
