@David-TP +1 to the reques, Got my Deco XE75, i can separate out 6ghz but not the 2.5/5ghz ones, this is ridiculous, the entry level wifi 6 router from TP-Link (AX1500) has lot of options including the MESH support, this being the premium router doen not have all the basic options, like the VPN and multi SSID support

  @David-TP 

I have a Worx Landroid m500 robot-mower, a Roborock S6 Maxv and smart lights fra Ledvance. 

They all require 2.4 network. 

Will I be able to get them to connect any deco mesh network? 

Dear  @David-TP , 

I'm still stuck with this problem with my smart devices which are most of them only supporting the 2.4

My devices : 

- Sonoff miniR2 with HAA (ravensystem) firmware (/RavenSystem/esp-homekit-devices)

- Heater Heatzy

- Netatmo weather station

All devices are managed throught Homekit/Homepod Mini and it need to be all in same network. 

So, you mentionned on the third point "An isolated IoT network for smart devices only" do you have any news regarding this update ? It has been "under evaluation" since 2,5 years... Are you sure to work on it ? 

Thank in advance for your clarification.

  @David-TP 

+1 to enable option for separate SSID.

In my case I have a problem where my devices do not switch between devices and lot of time it try to stay with deco which is far away. Probably switching only to 5ghz would be best in this case as it would cut off signal and reconnect. 

Also I need 2.4GHz enabled not as guest network because I want it in same network accessible so I cannot use your suggested option.

  @David-TP 

We definitely need this option.  My 5G devices are connecting at 2.4G most of the time, so I have to disable 2.4G to get them properly connected.  The main thing is we want the flexibility to separate our 2.4G and 5G so that we don't have to configure NIC connections on alll our devices to force to 5G.  It's better to just offer 2.4G and 5G as a separate network.  Heck, you have it for 6g and 5G, so why not go one further for 2.4G.  It just makes sense.  Your routers do it.  

 Right now, my ecobee thermostat is not functioning online as a result.

  @David-TP please this is one of the most voted features, why you don't even considered the implementation?... If is not possible because technology limitations, you can simple reply saying that current devices doesn't have those capabilities.

But if it is possible through a framework update, please make a effort and implement this feature, the community really need it.

In my case, I have Deco X20 and same error than other people, many times the mesh doesn't take the correct desition and force to keep my capables devices stuck in 2.4Ghz when I really want connect those to 5Ghz, even if I am beside to the mesh. That could be easy fixed if we can separate bands...

  @David-TP I'm returning my deco xe75 mesh system for the same reason. They should have provided an option to set up 2.4 & 5 GHz bands separately.

I have been using AX10 wifi 6 router which has this option. It's a basic setting. C'mon Tplink team. 

  @David-TP 

The devices tend to connect to 2.4 GHz with a significantly lower bandwidth. I had a non mesh TPLink dual band router in each room with ethernet backhaul and I could choose the 5 GHz for higher bandwidth. Now the devices connect to 2.4 GHz and I am not able to do anything. Disabling 2.4 GHz is not an option as many smart devicea work only on 2.4 GHz.

How do I make a device connect only to 5 Ghz without disabling 2.4 GHz

  @David-TP , I just received and installed 2 XE75Pro Decos for the mesh capability and 6GHZ back haul (I am coming from a LinkSys Router with wired extenders solution), and was completely blown away that separate SSIDs for 2.4 GHz and 5GHz is not available.  I turned on the Guest Network "workaround" and it works fine, but then an actual guest network is not available. 

Can we please get a confirmation if this will be implemented with a future firmware upgrade for XE75Pro Decos and other models? 

Otherwise I will be returning this system. 

There are way too many variables and thus situations in which a single SSID for 2.4 GHz and 5GHz results in a poor experience that it should at least be an option to separate them.

Thanks!
