Model: RE200  
Hardware Version: V4
Firmware Version: 1.0.8 Build 20210916 rel 59255 (6985)

I have Archer C64 and Re200 ...  (mesh mode)
If I change  5GHz channel on Archer C64 (36/40/44/48)  - it was changed, and  i see on wi-fi analyzer device 

But! I can see that channel on RE200 all time is 36!  I see it on analyzer and on web interface Re200 ... 36. 
1.  Why channel is not chaned automatically  identically? 

2.  Why І can't сhange the channel manually on RE200 between 36-48  ?

You cannot change the Wi-Fi channel manually on your TP-Link RE200 because EasyMesh architecture centralizes network management, forcing all satellite nodes to follow the main router's settings.
When configured as an EasyMesh satellite, the range extender locks its configuration and automatically clones the channel, network name (SSID), and security settings directly from your host router.
Why You Can't Adjust the Channels
  • Centralized Control Protocol: EasyMesh is designed to create a single, seamless network topology. Individual adjustments on satellite nodes are disabled by design to prevent network fragmentation.
  • Dynamic Backhaul Coordination: The RE200 uses its 5GHz band to maintain a wireless backhaul link with the main router. If you change the channel on the extender independently, it will break its connection to the router entirely.
How to Change the Channel Correctly
To change the 5GHz channel on your mesh system to a number between 36 and 48, you must execute the change from your main router's settings instead of the extender.
  1. Log into your Main Router's Web Management Gateway (e.g., TP-Link Router Portal).
  2. Navigate to Advanced > Wireless Settings.
  3. Locate the 5GHz Wireless Band settings.
  4. Change the channel selection from "Auto" to your preferred specific channel (36, 40, 44, or 48).
  5. Save the configuration and let the router apply changes.
Once modified on the main router, the EasyMesh configuration protocol automatically synchronizes and pushes the newly selected 5GHz channel down to your RE200 within a few moments.

Well, my assumption is that on the Wi-Fi Analyzer you saw the so-called Locked Backhaul Connection: The satellite uses a dedicated channel to talk to the main router. If you change it independently, it will break the connection and lose the network.

  @terziyski  on RE200 all time is 36 chanel, and in settings label , and in analyzer ...
And it`s so  bad because   my neighbors  overload this channel  ((

Hi,

 

For some reason that we don't know TP-Link decided it should be that way. You can't change this behavior. It is the same on other RE devices that use the same hardware platform, like my RE305 V4.

 

The web GUI of the RE in EasyMesh mode shows that its 5 GHz band is set to "Auto"matic channel selection, of which it indeed makes use. My RE305 seems to prefer channel 48.

 

The problem with that is, if the 5 GHz channel that is automatically chosen by the RE is different from the 5 GHz channel of the main EasyMesh router, it breaks the wireless 5 GHz EasyMesh backhaul, so the wireless EasyMesh backhaul will be done via the slow 2.4 GHz band.

not true..
 my speed on 2.4 Ghz   ~  20-28  Mbit\s .. 
 my speed on 5 Ghz   ~  60-80  Mbit\s .. 

But why 36 channel on all time?    Its mystery

What do you mean by "not true"?

 

If your router is on channel 40 or 44 or 48 and the RE200 on channel 36, does the icon for the 5 GHz backhaul show in grey color (= not connected) or in blue/cyan color (= connected)?
