Hardware Version: V20
Firmware Version: 1.2.11 Build 20240724 38913

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.

  @David-TP thanks.  I received the email and replied accordingly.  

 

As stated in my email response, Fast Roaming and Beamforming are OFF and the issue presists.
